Subject: libvmf,cpp,rauboot,mkstr(1) fixes, ld feature (#441)
Index:	usr.lib/libvmf,lib/cpp,sys/mdec/rauboot.s,... 2.11BSD

Description:
	1. The libvmf (virtual memory using tmp files) routines could crash
	   or hang an application if too many locked segments were requested.

	2. The C preprocessor (cpp) had a memory leak which could cause it
	   to run out of memory _and_ also failed to check the return
	   status of calloc() which would cause cpp to fail ungracefully.

	3. The MSCP bootblock would not work with a CMD CQD220 adaptor due
	   to the bootblock relying on the (undocumented?) behaviour of DEC
	   adaptors.

	4. In the mkstr(1) manpage the usage example given used lseek(2)
	   incorrectly.

	5. The linker (ld) does not accept the '-g' flag which on other
	   systems says to retain debuggin symbols.

	6. creat() is no longer a system call, thus it is an error to
	   have creat(2) instead of creat(3).

Repeat-By:
	Observation.

	Alternatively have Anders Magnusson beating on the system and
	submitting bug reports on a regular basis :-)

	The change to ld(1) is for compatibility for the same reason that '-z'
	was added a long time ago.  Eventually perhaps extra debug information
	will be generated by the compilers.

Fix:
	The following files are removed/added/modified by this update:

	added: /usr/src/man/man3/creat.3
	removed: /usr/man/cat2/creat.0
	removed: /usr/src/man/man2/creat.2

	modified: /usr/src/usr.lib/libvmf/vmf.c.old
	modified: /usr/src/sys/mdec/rauboot.s.old
	modified: /usr/src/bin/ld/ld.c.old
	modified: /usr/src/lib/cpp/cpp.c.old
	modified: /usr/src/lib/cpp/Makefile.old
	modified: /usr/src/man/man1/mkstr.1.old
	modified: /usr/src/man/man2/Makefile.old
	modified: /usr/src/man/man3/Makefile.old
	modified: /VERSION.old

	The file attached below is a shar file containing:
		
		441.sh - a script to remove the two manpages 
		441.shar - a shar file to add the new manpage
		441.patch - a patch file to modify the remaining files

	To apply this update cut where indicated and save to a file (/tmp/441).

	Then:
		cd /tmp
		sh 441
		./441.sh
		sh 441.shar
		patch -p0 < 441.patch

		cd /usr/src/usr.lib/libvmf
		make
		make install
		make clean

		cd /usr/src/lib/cpp
		make 
		make install
		make clean

		cd /usr/src/bin/ld
		make
		make install
		make clean

		cd /usr/src/man/man1
		/usr/man/manroff mkstr.1 > /usr/man/cat1/mkstr.0

		cd ../man3
		/usr/man/manroff creat.3 > /usr/man/cat3/creat.0

		cd /sys/mdec
		make
		make install
		make clean

	And with that you're done.

	As always this and previous updates to 2.11BSD are available via
	anonymous FTP to either FTP.TO.GD-ES.COM or MOE.2BSD.COM in the
