Basically it's there to handle Guile being already compiled into make,
via direct linking at build time, in a generic way.  If it was linked
then the global symbols would be found without needing to load anything.
However this particular issue could just be handled by the #define that
links it.

It's up to you how you think it best to implement, whether it makes more
sense to try to reimplement POSIX functions, or do it at a higher level.
Whatever is simpler.
