Hi John,

many thanks for the bug report - I've added LDFLAGS to the mc link on
the:  gm2+gcc-5.4.0 branch, gm2+gcc-6.4.0 branch and gm2+gcc-svn-trunc
branch.  Are you able to build gcc-5.4.0 rather than gcc-5.2.0 ?
(or gcc-6.4.0 ?).  I've built and run the regression tests on gcc-5.4.0
with this change - and all is ok on a GNU/Linux x86_64 system.
gm2+gcc-6.4.0 might be attractive as it has the runtime overflow patches
for NaNs detection and partial integer overflow detection

regards,
Gaius
