comparison functions to always use POSIX strcasecmp(). For non-POSIX
systems that use other functions (strcmpi or stricmp) use a macro to alias
strcasecmp to those. If we can't find any of them (VMS, plus whatever
UNIX doesn't have them) then define our own version in misc.c.
Invent a new macro HAVE_DOS_PATHS and change various instances of:
#if defined(WINDOWS) || defined(__MSDOS__)
to use the new macro instead. This should help make the OS/2 port
cleaner, as well.
Invent a cvs-clean maintainer target that tries to get the workspace
back to the state it was in after a CVS checkout.
New language.
Incorporate "order-only" prerequisites patch. Wrote a test for it.
The test shows what might be a bug in the code; I need to look at it
more closely (anyway it doesn't behave as I expected). Also I haven't
done the docs yet.
