Timo, there is what might be considered a better way to determine what type of
system a given package is being compiled on.  That is, the reserved defined 
symbols in cpp(1).  For example:

System			Symbols Defined By cpp(1)

AT&T 3B2		unix u3b2
AT&T 3B5		unix u3b5
AT&T 6386		unix i386
AT&T 6486		unix i386   (Oh well, it's still in CI)

etc....

I beleive most (hopefully all) vendors have defines for their unique
systems in their cpp(1) program.  I do not have available other vendors
systems at this time, however, so I cannot verify that or list the defines.
Perhaps other netters could fill you in about these.

If these defines are used to select Berkley/Sys V then hopefully, checking
include files, which may change, will be unnecessary.


Hope this is helpful,
(It really does make porting easier...)
