Continuing in my efforts to get a cygwin-free compiler for windows.
I managed to build gmp and mpfr for i586-mingw32msvc from linux.
I modified the build-mingw32ce script to add the proper --with-gmp and
--with-mpfr parameters to gcc's configure when host!=build.
Now the failure is at cc1-dummy.exe:

Basically, here, we try to link mingw code with linux code.
There is a cross compile problem, because of this config/i386/msformat-c.o
file that gets compiled for linux instead of being compiled for mingw.
But mingw prepends some _ to symbol names , and linux doesn't, so the
integer_types symbol in msformat-c.o should be _integer_symbol.
The configure/make/etc build process is quite frustrating when you're not an
automake guru.
and the gcc bootstrap process is an additional pain.
Do someone know where, and how, could I start to have an influence on this
badly cross-built file?
