__unix not defined

[Cavendish McKay <cmckay@morte.com>]

I'm trying to build a plotting library, and the code checks to see if
__unix is defined, but not __unix__.  It appears that while __unix__ is
defined, __unix is not.  Should the code in question check for both __unix
and __unix__, or is this a problem with my build/configuration of gcc?
Im using gcc 2.95.2 on OpenBSD 2.7
