[Mingw-cross-env-list] C++ program incorrectly linked as C under autotools

[Natalie Tasman]

I've set LT_INIT and LT_LANG([C++]); .cxx files are compiled correctly
with g++ but linking is happening with gcc and failing (missing all
the basic c++ stuff).   I don't know if this is relevant but in
Makefile.in the default "LINK" definition uses CC rather than CXX.

This works on a native system but not under mingw-cross-env.

Any suggestions would be very appreciated!


Thanks,

Natalie
