Hi
 
Many thanks for your reply.
 
I wonder whether you could guide me step by step.
 
Please see my comments below.

Do you mean MSYS base system, technology preview: msys-1.0.11 from Dec 4th, 2007 and tools for msys-1.0.11 from Set 20th, 2007.
 
Where do I "tar -zxvf" them?   Do I need all the packages listed on sourceforge?

I think I will for the new binaries. Is that ok?

Where do I find GMp and MPFR? GMP seems to be on of MSYS tools, doesn't it?  I couldn't find MPFR!

I am used gcc-4.2.1-build to find the problems with GMP and MPFR.
