Hi,

Here is a new patch set to for a new mingw cross build to build
guile.exe.  As discussed
(https://lists.gnu.org/archive/html/guix-devel/2016-04/msg00620.html) it
uses CROSS_C_INCLUDE_PATH and friends instead of CROSS_CPATH for cross
builds.

If you build hello.exe it will run under wine, guile.exe still crashes.
I am looking into that, that is to say, I did one attempt to install
cygwin's gdb in wine that did not succeed yet...more todo.

Greetings,
Jan
