[fpc-devel]Unix Renamefest

[Marco van de Voort]

FYI:

Currently I'm renaming nearly all {$IF(N)DEF Linux} to {$IF(N)DEF Unix} in
the development branch.

This because the meaning of the Linux directive is going to change in 1.2;
from now on, Linux will only signal real Linux specific behaviour, while the
directive "Unix" should be used for more generic Unix like features (like
forward slashes, Unix'like disc layout).

The development and fixbranch compiler will define:

for target		defines
FreeBSD			FreeBSD,BSD,Linux,Unix	(but Linux will 
						disappear in 1.2)
Linux			Linux,Unix

However since 1.0.2 doesn't support this, some arrangements in the makefiles
will be made to make the conversion smooth.

-----------

This is all part of a greater plan of course, namely the splitting up of the
LINUX unit into a Unix and Linux unit, more or less along the same lines
(everything which is a bit generic to Unix, while Linux specific stuff stays
in Linux)

This keeps the Unix unit a little more "portable" across Unices, while at the 
same time it removes the break on adding new functions to Linux.
