One ``problem'' with Linux is that it uses GNU libc, so expect it to
support any weird function out there.

Somebody (you?) should coordinate the effort.  Everybody else should
submit their contribution to that person.  When the time comes to
review the results, if the file is too long, it can be uploaded to
DJ's and put into the v2/.alphas tree on SimTel.

Any Unix is a superset of POSIX.  The extensions is where they differ.

Here's another suggestion:

  @subheading Portability

  @multitable {Supported}     {ANSI}   {POSIX}   {Unix}   {MS-DOS/MS-Windows}
  @item	      Supported? @tab   no @tab yes @tab (1) @tab (2)
  @end multitable

  (1) SysV flavor doesn't frobnicate the foobar.  BSD does.  Many Unix
      systems don't have the prototype declared anywhere (so it's best
      to have an explicit prototype in the program).

  (2) Known to be buggy in Borland.  DOS compilers declare prototype
      in @code{<io.h>}.

I suggest to use the latest v2.02 alphas as the baseline.  It will
make it easier for DJ to apply the changes.
