Maybe I am confused about something, but it is my impression that the
gcc for Windows built by MXE _is_ the MinGW gcc.

Normally, MXE builds gcc 4.7.2. That is not possible on my machine
because gcc's build system as of that version breaks with texinfo
version 5.0 installed on the host. So I changed the MXE Makefile to
build gcc 4.8.0 instead. After patching an issue with gettext/libintl in
gcc 4.8.0 I was able to complete the build with MXE.

For the record, I have attached those changes as a patch.

I only have OEM versions, and I don't think I am allowed to install
those in VirtualBox. Oh well, I guess I'll test it at work then.
