Hello!
In preparing an update of the FreeBSD port of m4 (currently at the 1.4.4) to
1.4.6, I noticed the following minor nits:
. Although FreeBSD's getopt.h is detected as sufficiently capable
by configure, the getopt.c and getopt1.c are still compiled and
linked into m4, instead of relying on the libc's versions
. FreeBSD's -lgnuregex is ignored, requiring an explicit
`--without-included-regex' and minor patching to src/Makefile.in
to add -lgnuregex to LIBS
. mkstemp_safer appears to be redundant -- how can mkstemp possibly
return the STDIN_FILENO?
. Although *snprintf code is compiled and linked into libm4, none of
these functions make it into the m4 executable -- are the files
obsolete?
. The comment in strcase.m4 states, that no existing system provides
multi-byte correct strcasecmp -- is there a test one can run to check
a particular system? If I were to patch m4 to use the libc's
strcasecmp,
would running `gmake check' detect a problem, if there were one?
Any comment? Thank you very much!
