Gavin, thanks very much for your help. Just in case someone reads
this discussion later, I found that there was a small syntax error in
the above. The following is what finally worked for me (a small
change after ac_cv_have_C__func__='no'):
# Test for C compiler __func__ support
if test "$ac_cv_have_C__func__" != 'yes' ; then
AC_CACHE_CHECK(for C compiler __func__ support, ac_cv_have_C__func__,
[AC_COMPILE_IFELSE([AC_LANG_PROGRAM([[]],
[[const char *func=__func__;
return (func != 0 ? 0 : 1);
]])],
[ac_cv_have_C__func__='yes'],
[ac_cv_have_C__func__='no'])])
if test "$ac_cv_have_C__func__" = 'yes' ; then
AC_DEFINE(HAS_C__func__,1,Define if C compiler supports __func__)

I now have the GraphicsMagick configure script updated and apparently
working fine locally with Autoconf 2.69c.
There are still some deprecation warnings from an included m4 module.
