Bug#790781: FTBFS with GCC 5: error: mp.h: No such file or directory

[Martin Michlmayr]

Package: netrek-client-cow
Version: 3.3.0-3
Severity: serious
User: debian-gcc at lists.debian.org
Usertags: ftbfs-gcc-5

netrek-client-cow fails to build with GCC 5.  Even though the
configure script finds gmp.h, HAVE_GMP2_H is not set, therefore mp.h
is used instead of gmp.h.
