I used Autoconf 2.57 for building GCC 3.2.2 that you downloaded. I
also used automake 1.7.3.

Andris would have to answer this one, but bugs are found by Andris and
others in the DJGPP porting after the official GCC release is done and
as such a patch needs to be done.

I suspect that the docs have not been updated. A guess only. Try using
autoconf 2.57 and automake 1.7.3.

SNIP...

Check which versions of automake, autoconf, m4 you are using. On WIN
XP I use the following to do the build that you downloaded:-
	automake 1.7.3 (from 22-Feb-2003)
	autoconf 2.57 (just updated to srcv from 27-Mar-2003)
	M4 1.4 (latest DJGPP version from 8-Jan-2003)

These dates may be when I downlaoded them, so take of a few days/week
to get an idea of the date of the files on Simtel)

BTW Did you searh the DJGPP mailing list archive as there was allot of
discussion in this newsgroup last year about getting DJGPP cross
compiling on Linux and the developer who did it wrote up a doc and has
it available for download.
