Good catch.

Just confirming this, I tried building the Debian package on an IA64
machine and got this:

../foreign/openpgm/libpgm-2.0.20rc5/openpgm/pgm/time.c:137: warning: ‘tsc_to_ns’ defined but not used
../foreign/openpgm/libpgm-2.0.20rc5/openpgm/pgm/time.c: In function ‘tsc_update’:
../foreign/openpgm/libpgm-2.0.20rc5/openpgm/pgm/time.c:470: error: impossible register constraint in ‘asm’
make[3]: *** [libzmq_la-time.lo] Error 1

Which is indeed the "rdtsc" call.

That would be a shame :-)

Stephen or Malo could you comment on what we need to do to make this build
on non-x86 platforms?
