Note that this problem is with your C compiler, not with whatever fortran
compiler you may have chosen.

What options did you give to the "configure" script?
What do the "CC=", "CFLAGS=" and "LOADCC=" lines say in your config.h file?

It looks from the above like you are using the 64-bit version of ld, but
compiling things with the -m32 flag set. This would cause the error messages
you see, but we need more information to track down why this is happening.
