_G_config.h not picking up sigset.h on linux 2.0.35 + glibc 2.0.7 (RH5.1)

[Tkil <tkil at scrye dot com>]

I've been having this problem for a while (everything past 1.0
release).  I noticed that similar problems were reported about a year
ago:

   http://www.cygnus.com/ml/egcs-bugs/1997-Sep/0159.html

Jeff indicated at the time that some progress was being made -- Jeff,
do you happen to remember the status of that?

It's entirely possible that something on my machine is hozed, it's
been through quite a few combinations of manual upgrade + root
partition shifting and all that fun stuff.

If you would like more information on my system, please just ask.

config.status in my build dir says:

../egcs-1.1b/configure --with-gcc-version-trigger=/usr/local/src/egcs-dir/egcs-1.1b/gcc/version.c --host=i586-pc-linux-gnulibc2 --prefix=/usr/local --enable-threads --norecursion 

and the actual error:
