autoconf 2.12.1?

["Theodore C. Belding" <streak at umich dot edu>]

When I tried to build the most recent egcs from CVS, on i686-pc-linux-gnu
(RedHat x86 Linux 5.1) I get the following error:

% ../configure --prefix=/usr/local/egcs-19981130
[...]
% make
[...]
make[1]: Entering directory `/usr/local/src/egcs/obj/gcc'
cd ../../gcc; autoconf
FATAL ERROR: Autoconf version 2.12.1 or higher is required for this script
make[1]: *** [../../gcc/configure] Error 2
make[1]: Leaving directory `/usr/local/src/egcs/obj/gcc'
make: *** [all-gcc] Error 2

I had autoconf 2.12 installed, but I couldn't find a 2.12.1 release
anywhere, nor any mention of it in the web documentation.  I went ahead
and installed autoconf from the current CVS sources at
http://sourceware.cygnus.com/autoconf/ which seems to work.

Is that the recommended autoconf version, or is there actually a 2.12.1
release somewhere? (It's not at ftp://ftp.gnu.org/pub/gnu/)

Also, a suggestion: configure didn't complain at all about an outdated
autoconf; I got the error during the build.  Perhaps configure should
check specifically for autoconf version 2.12.1 or greater?  Configure
didn't check for gperf, either, which was missing from my system and was
needed for the compile.

Thanks!
