Re: [Mingw-users] MinGw 5.3.1 - What is needed to compile gcc-4.2.1-2-src.tar.gz?

Hello
 
Many many thanks.
 
A couple of more questions, if I may. Please see my comments below.

All extracted to c:\msys\1.0 ->  The package coreutils-5.97 created the c:\msys\1.0\coreutils-97
and under it bin, info, lib and man. I thought they should go directly to c:\msys\1.0.  Am I right?

Done.

Ok, but how to compile them?  Can I use msys environment?

Yes, it didn't find the appropriate GMP and MPFR and that was the reason of my question in the first place.

How disable DEP on Vista?

 
Once more, many thanks for the help and patience.
