include - 
	All otso header files go here or in subdirectories :
	 OTSO os, prepro, tools, etc, etc.

	This should make multiple inclusion of header files easier
	for makefiles.


changes:
23.5.91 EO

Because of porting to MSDOS, I renamed
- c++compiler.h to CCsetup.h (also in dvops.hxx and object.hxx)
- dasntypes.h to asntypes.h (also in frame.typ)
- isomacros.hxx to isomacro.hxx
- isoservices.hxx to isoserv.hxx
- voidgroup.hxx to voidgrp.hxx
- voidgroup.cxx to voidgrp.cxx
- voidgroup.* to voidgrp.* in /otso/dvops/Makefile
- previous *.hxx:s in headers.make
Hopefully they will compile!
