Hello,

I'm getting some build problems when attempting to compile git master
of CADO-NFS:

utils/relation.c now needs fgetc_unlocked, which neither OS X or
cygwin have

After working around that, in both OS X and cygwin I get

CMakeFiles/purge.dir/purge.c.o: In function `prempt_scan_relations_pass_two':
/home/jasonp/cado/filter/purge.c:1946: undefined reference to
`_pthread_tryjoin_np'

On 32-bit x86 I get

Note that it isn't a big deal for me if support for 32-bit x86 is too
cumbersome in the current codebase.
