When compiling a Win64 i686-w64-mingw32 compiler with multilib, ada fails to
build with similar errors as reported in
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37993 There is currently no
selection on the i686 side for multilib, as the gcc/gcc-interface/ada Makefile
assumes that no ix86 mingw* targets may be compiled multilib.
This can be fixed with something similar to the following trivial patch:
diff a/gcc/ada/gcc-interface/Makefile.in b/gcc/ada/gcc-interface/Makefile.in
--- a/gcc/ada/gcc-interface/Makefile.in
