Paul's suggestion seem to answer this, but I'd like to offer another
solution: always use the gnulib interface.  Scattering #if over your
code decreases the readability and quality of the code.  If you really
need to use the native functions, do it through a layered API that
allow users to select which implementation to use.  I use something
similar in GnuTLS, Shishi, GSASL etc to switch between Nettle and
libgcrypt; adding the BSD interfaces as well would be simple.  Then
your code would use the new layer everywhere, and the code will be
readable.
