Hi John,

thanks for the report - it is interesting as I'm seeing architectural
build problems on my x86_64 debian system.  Ie 32 bit objects in a 64
bit library! - so hopefully they are the same bug.  I'm also rewriting
libgm2/configure.ac and libgm2/Makefile.am (new file) which address the
cross compile and also hopefully the problem that we are seeing,

regards,
Gaius
