Correct me if I'm wrong, Alex, but I think you said you were using the
development version of CVS. I imported the latest getopt module from
GNULIB on October 6th, which, IIRC, is exactly when you began
encountering problems. Anyhow, whatever issue you are having should
be with GNULIB.
Glancing at the latest gl_GETOPT test, it appears to be only using the
existance of the getopt.h header file to decide whether to use the
substitute getopt() function or not:
AC_DEFUN([gl_GETOPT],
[
gl_PREREQ_GETOPT
GETOPT_H=
AC_CHECK_HEADERS([getopt.h], [], [GETOPT_H=getopt.h])
AC_CHECK_FUNCS([getopt_long_only], [], [GETOPT_H=getopt.h])
if test -n "$GETOPT_H"; then
gl_GETOPT_SUBSTITUTE
fi
])
So, it does make sense that, if Alex's version of BSD comes packaged
with a getopt.h header but an incompatible getopt() function, then the
latest gl_GETOPT would incorrectly choose to use the system getopt()
function rather than the GNULIB substitute.
Something like Alex's test program should probably be added to
gl_GETOPT, unless someone can suggest a better way to detect or work
around the problem.
Cheers,
Derek
