C compiler cannot create executables

[Lee Duke]

First, I'm new to the Gnu Autotools. I've looked through the archives
and if there is something in there relevant to this problem, I either
could not find it or didn't understand it.

Second, I'm running Fedora 4 with the latest updates. The version
numbers for the various programs are:
        (GCC) 4.0.2 20051125 (Red Hat 4.0.2-8)
        autoconf (GNU Autoconf) 2.5
Both were installed using yum and rpms--that is to say, I didn't put
anything in any weird places.

I'm getting an error with configure wherever I try it. What's really
strange--to me, anyway--is the configure function worked before I made
some upgrade, but I'm not sure which one caused it.

Okay.

Otherwise, gcc and g++ work fine. 

Thanks for your help.
