- add /usr/include/objc to mtree
- set libobjc/Makefile INCSDIR=/usr/include/objc
- put to-be-installed includes to libobjc/Makefile into INCS=
- add the Objective-C source files to the appropriate lists.
- as the objc include files are installed now, no need to patch most
of the files.
- add /usr/include/obj/* to src/distrib/comp/mi
The changes have been applied to gcc2netbsd, and this script was then used
to create the new version of the files in libobjc/.
Added a new patch mechanism to gcc2netbsd so changes from the FSF source
are seen in gcc2netbsd. Sync some Makefiles to output of current gcc2netbsd.
(Cosmetic changes only to the Makefiles.)
