Are the functions intended to have the same semantics?  If so, perhaps
you should arrange to use the FreeBSD versions while on FreeBSD.  If
not, perhaps the gnulib versions should be renamed.

If they are supposed to have the same semantics but the FreeBSD
versions are buggy, you could rename the functions in unistd.h
instead, by using #define before #include <unistd.h>.  It's a bit of a
hack, as it requires that client code to include your .h file before
it includes unistd.h.  I suppose another possibility is to use linker
magic but this is a bit less portable in practice.
