Hi Joe

In our linux systems here these kind of system macros are set in the
header file /usr/include/features.h, which is include by just about any
of the other includes in /usrc/include. So probably there is a similar
one on you BSD system. I you could send this file or look into it and
find out when BSD_VISIBLE gets set we may fix it the proper way.
