[Help-glpk] Compile error

Hi all,
I am trying to use the glpk libraries to implement an Octave (www.octave.org) 
LP function. I tried to install glpk, but I ran in an unusual compile error. 
It seems that gcc does not find the math.h header file, which is indeed 
in /usr/include/. However, the configuring reports that the ANSI C header 
files are found. Moreover, if I use a very simple test program (prova.c, 
attached), and I try to compile with gcc, I get an error of the same sort; if 
I compile with g++, however, everything works...

Does anyone know what's happening?

Compiler: gcc 3.3.3 20040412 (Gentoo Linux 3.3.3-r6, ssp-3.3.2-2, pie-8.7.6)

Attached: configure and make output, test file prova.c.

Cheers,
- -Federico
