Recommend -Wimplicit in CWARNFLAGS next. There are still a few hundred
potential arg mismatches because no function declaration is in scope.
Don't duplicate option `-I.'.
Remove null editing of the assembler source for all profiled objects.
The required magic has been done since prehistoric times by an
asm("mcount") declaration.
Simplify the clean rule.
Don't try to be clever about timestamps involving genassym. genassym's
timestamp usually got ahead of assym.s's timestamp, so `make' almost
always had to run genassym and compare *assym.s to decide that nothing
needed to be done. The cost is reassembling a few files whenever
genassym is rebuilt. Assembling is almost as fast as comparing.
Always go through genassym.o to build genassym. This would have avoided
numerous bugs involving mkdep -p. Now it just stops genassym from
depending on the name of the temporary object file.
Use ${CFLAGS} for building genassym. Mainly ${CWARNFLAGS} were missing.
1) cut this up into /sys/sys/inflate.h, sys/kern/inflate.c
sys/kern/ingact_gzip.c
2) make a lot more things static
3) make a lot of globals const
4) make some args const
5) first stage of making globals into a struct (not used yet)
The vm_allocate() call which was introduced between revisions 1.4 and
1.5 of imagact_gzip.c broke things. I have backed that out for the time
being. (Davidg: help please)
WARNING: if you have gzip enabled in your kernel, you must now run
config again, as another source file has been added. Otherwise your
kernel compile will fall over.
This is all still WIP. More commits to come.
Suggestions from: phk.
WARNING: THIS MATERIAL MIGHT GO AWAY!
This material needs the core-groups approval to stay here for the 2.0 release.
If the core-group does not concent to this commit, it will be backed out.

It is a non-gpl'ed "unzip" which will allow execution of a.out files which
have been sent through "gzip -9". The idea being saved disk-space.
Just now this code has quality rating: "working prototype".
To compress a file to be used with this, do it exactly this way:
gzip -9 -v < /bin/FOO > /tmp/FOO
remember to chmod /tmp/FOO as needed.
DON'T compress all of you binaries right away ! There are several things
which you should consider first:
1. Using compressed binaries, you use >MUCH< more VM, and thus swap-space.
2. It is slow.
3. It might crash your machine.
Apart from that, I welcome comments...
if requested. LKMs which need it should use:
SRCS+= vnode_if.h
CLEANFILES+= vnode_if.h vnode_if.c
These rules were already present for VFS LKMs; now they are enabled all
the time. (VFS LKMs do not need the fragment above; it is still done for them.)
- Make a number of filesystems work again when they are statically compiled
(blush)
- FIFOs are no longer optional; ``options FIFO'' removed from distributed
config files.
