Hi!

Highlights in this iteration

   * removed indentation from commit messages
   * replaced and-let* with and=>
   * have added #:phases return #t
   * removed extra cross-gcc mingw configure flags
   * removed custom cross-gcc-mingw install phase
   * use name "libc" instead of "mingw-w64", allowing a clean-up
   * add some comments
   * document gcc-cross-environment-variables.patch harder

Usage
    ./pre-inst-env guix build --target=i686-w64-mingw32 guile

Greetings,
Jan

Subject: [PATCH 01/10] gnu: cross: Use CROSS_*_INCLUDE_PATH for system
 headers.

* gnu/packages/patches/gcc-cross-environment-variables.patch: Also use CROSS_
variants: CROSS_C_INCLUDE_PATH, CROSS_CPLUS_INCLUDE_PATH,
CROSS_OBJC_INCLUDE_PATH, CROSS_OBJCPLUS_INCLUDE_PATH to be used for system
libraries, see
https://lists.gnu.org/archive/html/guix-devel/2016-04/msg00620.html.
* gnu/packages/cross-base.scm (cross-gcc, cross-gcc-arguments, cross-libc):
Use CROSS_*_INCLUDE_PATH (WAS: CPATH).

+which lead to the previous iteration of this patch, introducing CROSS_CPATH,
+CROSS_LIBRARY_PATH and advocated the use of CPATH/CROSS_CPATH.
+
+As a concequence of the bug report
+
+    http://bugs.gnu.org/22186
+
+usage of C_INCLUDE_PATH was re-introduced.  As noted in he discussion at
+
+    <https://lists.gnu.org/archive/html/guix-devel/2016-04/msg00533.html>
+
+this introduces native headers in the search path and it was decided to keep
+using C_INCLUDE_PATH for system headers and introduce CROSS_C_INCLUDE_PATH et
+al., next to CROSS_CPATH to support cross compiling.
