Thanks a lot. In the gmp documentation it encourages you to build for the 
actual processor it will run on. For example I have a Pentium 4 processor so 
I reconfigured using `--build=pentium4-pc-msdosdjgpp'. Then as you already 
know in `gmp.h' the result will be `-mtune=pentium4 -march=pentium4' and 
when you compile mpfr and mpc it uses these values in CFLAGS. However I 
overkill and reconfigure both mpfr and mpc sources anyway. All tests passed 
using both GCC 4.4.2 and GCC 4.4.4.
