* job.c (construct_command_argv_internal): Don't discard an
explicit empty argument at the end of the command line. In the
slow case return immediately if the command line was empty.
* job.c (reap_children): Don't call die if handling_fatal_signal.
* job.c (start_job_command): Call block_sigs.
(block_sigs): New function, broken out of start_job_command.
(reap_children): Block fatal signals around removing dead child from
chain and adjusting job_slots_used.
* job.h: Declare block_sigs.
* job.c (reap_children): Quiescent value of shell_function_pid is
zero, not -1.
* job.c (start_job_command): Call block_sigs.
(block_sigs): New function, broken out of start_job_command.
(reap_children): Block fatal signals around removing dead child from
chain and adjusting job_slots_used.
* job.c (reap_children): Quiescent value of shell_function_pid is
zero, not -1.
* dir.c: WIN32 does not support inode. For now, fully qualified
pathname along with st_mtime will be keys for files.
Fixed problem where vpath can be confused when files
are added to a directory after the directory has already been
read in. The code now attempts to reread the directory if it
discovers that the datestamp on the directory has changed since
it was cached by make. This problem only seems to occur on WIN32
right now so it is lumped under port #ifdef WIN32.
* function.c: WIN32: call subproc library (CreateProcess()) instead of
fork/exec.
* job.c: WIN32: Added the code to do fork/exec/waitpid style processing
on WIN32 systems via calls to subproc library.
* main.c: WIN32: Several things added here. First, there is code
for dealing with PATH and SHELL defaults. Make tries to figure
out if the user has %PATH% set in the environment and sets it to
%Path% if it is not set already. Make also looks to see if sh.exe
is anywhere to be found. Code path through job.c will change
based on existence of a working Bourne shell. The checking for
default shell is done twice: once before makefiles are read in
and again after. Fall back to MSDOS style execution mode if no sh.exe
is found. Also added some debug support that allows user to pause make
with -D switch and attach a debugger. This is especially useful for
debugging recursive calls to make where problems appear only in the
sub-make.
* make.h: WIN32: A few macros and header files for WIN32 support.
* misc.c: WIN32: Added a function end_of_token_w32() to assist
in parsing code in read.c.
* read.c: WIN32: Fixes similar to MSDOS which allow colon to
appear in filenames. Use of colon in filenames would otherwise
confuse make.
* remake.c: WIN32: Added include of io.h to eliminate compiler
warnings. Added some code to default LIBDIR if it is not set
on WIN32.
* variable.c: WIN32: Added support for detecting Path/PATH
and converting them to semicolon separated lists for make's
internal use. New function sync_Path_environment()
which is called in job.c and function.c before creating a new
process. Caller must set Path in environment since we don't
have fork() to do this for us.
* vpath.c: WIN32: Added detection for filenames containing
forward or backward slashes.
* NMakefile: WIN32: Visual C compatible makefile for use with nmake.
Use this to build GNU make the first time on Windows NT or Windows 95.
* README.WIN32: WIN32: Contains some helpful notes.
* build_w32.bat: WIN32: If you don't like nmake, use this the first
time you build GNU make on Windows NT or Windows 95.
* config.h.WIN32: WIN32 version of config.h
* subproc.bat: WIN32: A bat file used to build the
subproc library from the top-level NMakefile. Needed because
WIndows 95 (nmake) doesn't allow you to cd in a make rule.
* w32/include/dirent.h
* w32/compat/dirent.c: WIN32: opendir, readdir, closedir, etc.
* w32/include/pathstuff.h: WIN32: used by files needed functions
defined in pathstuff.c (prototypes).
* w32/include/sub_proc.h: WIN32: prototypes for subproc.lib functions.
* w32/include/w32err.h: WIN32: prototypes for w32err.c.
* w32/pathstuff.c: WIN32: File and Path/Path conversion functions.
* w32/subproc/build.bat: WIN32: build script for subproc library
if you don't wish to use nmake.
* w32/subproc/NMakefile: WIN32: Visual C compatible makefile for use
with nmake. Used to build subproc library.
* w32/subproc/misc.c: WIN32: subproc library support code
* w32/subproc/proc.h: WIN32: subproc library support code
* w32/subproc/sub_proc.c: WIN32: subproc library source code
* w32/subproc/w32err.c: WIN32: subproc library support code
* job.c: No Pipes on Amiga, too
(load_too_high) Neither on Amiga
ENV variable on Amiga are in a special directory and are not
passed as third argument to main().
* GNUmakefile (globfiles): Add AmigaDOS support files.
(distfiles): Add $(amigafiles).
(amigafiles): New variable.

* Added Amiga support in commands.c, dir.c, function.c,
job.c, main.c, make.h, read.c, remake.c
* commands.c: Amiga has neither SIGHUP nor SIGQUIT
* dir.c: Amiga has filenames with Upper- and Lowercase,
but "FileName" is the same as "filename". Added strieq()
which is use to compare filenames. This is like streq()
on all other systems. Also there is no such thing as
"." under AmigaDOS.
* function.c: On Amiga, the environment is not passed as envp,
there are no pipes and Amiga can't fork. Use my own function
to create a new child.
* job.c: default_shell is "" (The system automatically chooses
a shell for me). Have to use the same workaround as MSDOS for
running batch commands. Added HAVE_SYS_PARAM_H. NOFILE isn't
known on Amiga. Cloned code to run children from MSDOS. Own
version of sh_chars[] and sh_cmds[]. No dup2() or dup() on Amiga.
* main.c: Force stack to 20000 bytes. Read environment from ENV:
device. On Amiga, exec_command() does return, so I exit()
afterwards.
* make.h: Added strieq() to compare filenames.
* read.c: Amiga needs special extension to have passwd. Only
one include-dir. "Makefile" and "makefile" are the same.
Added "SMakefile". Added special code to handle device names (xxx:)
and "./" in rules.
* remake.c: Only one lib-dir. Amiga link-libs are named "%s.lib"
instead of "lib%s.a".
* main.c, rule.c, variable.c: Avoid floats at all costs.
* vpath.c: Get rid of as many alloca()s as possible.
Test it only after calling start_job_command for a new command line.
When no more cmds, just set C->file->update_status.
(start_job_command): When the last line is empty or under -n, set
C->file->update_status.
(start_waiting_job): Grok cs_not_started after start_job_command as success.
(new_job): Set C->file->update_status when there are no cmds.
(job_next_command): When out of lines, don't set CHILD->file->update_status or
CHILD->file->command_state.
(PATH_SEPARATOR_CHAR): New macro; differing defns for [__MSDOS__] and not.
[__MSDOS__] (dos_pid, dos_status, dos_bname, dos_bename, dos_batch_file):
New variables.
(reap_children) [__MSDOS__]: Don't call wait; just examine those vars.
(unblock_sigs) [__MSDOS__]: Do nothing.
(start_job_command) [__MSDOS__]: Use spawnvpe instead of vfork and exec.
(load_too_high) [__MSDOS__]: Always return true.
(search_path) [__MSDOS__]: Check for : or / in FILE to punt.
Use PATH_SEPARATOR_CHAR instead of ':'.
(construct_command_argv_internal) [__MSDOS__]: Wholly different values for
sh_chars and sh_cmds. Wholly new code to handle shell scripts.
