-/*  Yes, that's right:  of all the platforms supported by ppp, 
-    only Mach OpenStep 4.x doesn't support POSIX.  Sheesh.
-
-    Stranger still, the POSIX declatations are still in the 4.x header files,
-    and the gcc -posix still defines _POSIX_SOURCE.  So... 
-    we emulate (sometimes badly) the missing POSIX functions.  This
-    is by no means a complete or general POSIX emulation.  Just enough 
-    to get us by for ppp, so we don't have to pollute the rest of the 
-    sources of every other (non-braindead) platform.  Much of the
-    code was snarfed from NeXT's 4.0 ppp port, the rest inspired by
-    "POSIX Programmers Guide" by Donald Lewine.
-    
-    Maybe if we complain NeXT will upgrade to BSD4.4 libs like the rest of
-    the free world (and maybe pink elephants will fly out of my...  -KC)
