[Bug: 21.5-b28] Found cause of --with-union-type error

The error appears to be caused by a bug in the way autoconf deals
with
WORDS_BIGENDIAN when configure runs on a G5.
The resulting src/config.h from autoconf 2.63 places
/* #undef WORDS_BIGENDIAN */
in src/config.h whereas 2.62- and 2.61-created configurse add
#define WORDS_BIGENDIAN 1
to src/config.h
That seems bad.
When a 2.62 (or 2.61) created configure runs, it says
checking whether byte ordering is bigendian... yes
but 2.63 script says
checking whether byte ordering is bigendian... universal
They are different answers (on my G4 Mac OS X 10.4.11 2.63 still says
"yes"), but why it matters I don't understand. I guess I'll have to
back up to 2.62 for the moment.
Could this point to the potential for even more subtle bugs
Yes, but there's not much we can do about "potential" unless somebody
is willing to do the work of porting our whole configuration script to
a better system. We're stuck with autoconf for now, and will have to
put up with the bugs.
Thank you for the report.
