This is the memory-mapped-files egg, which is a dependency of spiffy.
The MAP_ANON definition is marked as deprecated on GNU systems in favour
of MAP_ANONYMOUS, but other systems still hang on to MAP_ANON, sometimes
offering an alias as MAP_ANONYMOUS.  I've now changed it so that if
MAP_ANONYMOUS is undefined but MAP_ANON is defined, it is made an alias.

I've published a new release, which should appear on the egg servers shortly.

Cheers,
Peter
