Reoder of the makedefs/makedirdefs to fix Mac OSX compilation. Sent in by
Bob Kuehne.
the DIRS cruft in a single file in the Make directory instead of having
to edit multiple files. Also edited Makefiles that needed to include
this file.
Also cleaned up txp loader to compile with SunOS. This needs to be retested
on other platforms.
the Make directory is left with four files only :
makedefs
makerules
makedirrules
instrules
These work for all platforms supported so far, which include :
Linux
Irix
Solaris
MacOSX
Cygwin
FreeBSD
