I'm going to guess you had something to do with the manual.
:)
I just read the description at:
http://www.gnu.org/manual/autoconf/html_mono/autoconf.html
and I understand it now, but I'm sure it didn't sink in
the first time. Unlike the gnumake manual, (which is great),
there's no example.

I didn't know about GCC, but my bigger problem was
I thought the code was coming
from autoconf. When I went looking for the code in configure.in
I was searching for the f77 part of the code. Since its not in
stuff generated by autoconf 2.13, I guessed the whole test was
coming from autoconf.
I know, my understanding of autoconf macros is abysmal,
but I think I'm improving.

I think different versions of autoconf is an issue too.
2.57 is complaining about our input files, but it seems to work.
I just updated the notes I keep about preparing releases to
tell myself to do a compile with Sun's compiler before release.
Seems like a good idea with gcc having weird extensions.
Thanks.
