Thanks.  I've implemented these, as well as Paul and Ralf's other
suggestions.  I've added all these to c.m4, and the diff against the
c.m4 in 2.59a is attached.

One change I've made is added arguments to AC_PROG_CC_C89,
AC_PROG_CC_C89 and AC_PROG_CC_STDC to allow custom code to run on
success or failure, to e.g. abort configure if there isn't a C99
compiler available.  It should be completely backward-compatible with
existing code.  Is this OK?

Any comments will be gladly received.  (Apologies if the formatting is
a little weird--it's over two years since I last wrote any m4 other
than basic configure scripts.)

I can re-do the diff against autoconf CVS if required--I just don't
have a copy right now.


Regards,
Roger
