#10 Doesn't build on Fedora Core 3

[FX]

Trying to build Wcalc-2.1 on Fedora Core 3 gives:

Fedora Core 3 has flex 2.5.4, gcc 3.4.4, gmp-4.1.4.

It looks like you don't have MPFR installed. Unfortunately, GMP comes
with a broken version of MPFR that many lazy packagers turn on in their
package because they don't want to go through the trouble of packaging
the real MPFR (I really wish they wouldn't do that). The broken MPFR
included in GMP is sufficient for the configure script to think that it's
found a working MPFR. Unfortunately, it looks like Fedora doesn't have
a real MPFR rpm available. There's a source rpm available on the MPFR
web page that you should be able to use: http://www.mpfr.org/mpfr-
current/

I'll try and modify the configure script so that it won't be fooled by GMP's
broken MPFR, but what you'll need to do in any case is get a working
version of MPFR.
