Yeah, I thought about that as well. But I'm not sure if 'isunix' should 
be taken to literally. I mean, GNU/Linux isn't unix, but I don't think 
that 'isunix' should return false for GNU/Linux. I'm guessing the 
'is[unix|pc|mac]' functions would most often be used like this:

if (ispc())
  # windows code here
elseif (isunix())
  # BSD/Linux/Solaris/AIX/etc code here
elseif (ismac())
  # OS X code here
else
  error("Unknown OS")
endif

But since I only use GNU/Linux I'm only guessing here. I never really 
think about writing cross-platform code...
