is because the DJGPP `ln' emulates soft links for executables by
generating a stub that in turn calls the real program. This
feature also works with nonexistent files like in the Unix
spec. So `ln -s X conftestdata' will generate `conftestdata.exe'
which will attempt to call 'X.exe'. But this feature only works
for executables. Fix it.

of $ac_xdir. Not only is `test -e' not portable, but the test isn't
necessary at all; the following mkdir ends up accomplishing the
same goal. Suggestion from Alexandre Oliva.
* acgeneral.m4 (_AC_INIT_PREPARE_ENVIRONMENT): New macro.
Handle the NLS envvars, and IFS.
(_AC_INIT_PREPARE): Use it, no longer set the NLS envvars.

Likewise.
* acspecific.m4 (AC_FUNC_SELECT_ARGTYPES): Use a single cache
variable instead of three.

* libm4.m4 (ifndef): New macro.
* acgeneral.m4 (AC_DIVERT): New macro, maps a diversion name to
its value. The diversions now have a short name, e.g., `NOTICE',

within the `AC_DIVERT' name domain.
Adjust all callers.
* acspecific.m4: Adjust all callers.
headers if they exist (needed for some missing prototypes) and
corrects the signal handler prototype/definition. The signal
handler prototype is now prepended with an `extern "C"' for C++
compilers since some platforms explicitly require an `extern "C"'
signal handler.
