--- Comment #7 from Denis Excoffier <gcc@Denis-Excoffier.org> ---
Here are the config.log found at top level and the config.log at
i686-pc-cygwin/libgcc level (see attachments).

What do you need more specifically?

I have to say that i use gmp-6.0.0a, mpfr-3.1.2 (without patches), and
mpc-1.0.2, all of them untarred in the source tree. All of them work well for
building GCC 4.8.2.
