* various: Changed !strncmp() calls to strneq() macros.
* misc.c (sindex): Make slightly more efficient.
* dir.c (file_impossible): Change savestring(X,strlen(X)) to xstrdup().
* implicit.c (pattern_search): Ditto.
* main.c (enter_command_line_file): Ditto.

* variable.c (define_variable_in_set): Ditto.
(define_automatic_variables): Ditto.
* vpath.c (construct_vpath_list): Ditto.
* misc.c (xrealloc): If PTR is NULL, call malloc to conform to
the standard--some older versions of realloc are non-standard so
make xrealloc DTRT.
* main.c (main): Call xrealloc() directly instead of testing for
NULL.
* function.c (func_sort): Don't try to free NULL; some older,
non-standard versions of free() don't like it.
* configure.in (--enable-dmalloc): Install some support for using
dmalloc (http://www.dmalloc.com) with make. Use --enable-dmalloc
with configure.
