without clobbering cexp.c, and there were no missing dependencies on
cexp.h because cexp.h isn't actually used.
Fixed style bugs.
sources. This will be used to fix `make -jN' races in many
Makefiles in /usr/src, and to simplify these and other Makefiles.
To get the fixes and simplifications, application Makefiles should
put the raw lex and yacc source names (foo.l and bar.y) in SRCS and
not put the names of any generated files in SRCS or CLEANFILES. A
few Makefiles already do this, although it didn't actually work before
(mkdep couldn't create complete dependencies because there is no
intermediate .c file for the .y.o and .l.o implicit rules).
Complications: if bar.y is in SRCS and -d is in YFLAGS, then bar.h
will be generated whether or not it is used, even if this clobbers a
real source file. This is so that bar.c can be generated using the
-j-safe and debugger-friendly -o option to YACC. There are smaller
warts for handling y.tab.h. y.tab.c and lex.yy.c are not supported.

default, at least in BSD. This used to be automatic, because chown(2)
didn't follow symlinks. When chown(2) was changed to follow symlinks
in BSD4.4, chown(8) was changed to not follow symlinks by default.
The previous commit broke this. The first victim was bsd.prog.mk,
which uses a plain chown in an attempt to change the ownership of the
symlinks to `dm' in /usr/games. This fails when it is done before
dm is installed, or messes up the ownership of dm if dm is installed.
Unfixed problems:
1. When lchown(2) was implemented, chown(8) wasn't changed to implement
the historical behaviour of changing ownership of symlinks. I'm not
sure if it should have been. The -HLP options give more complete
control, but they unfortunately don't apply unless the -R option is
specified (a problem shared with other commands, e.g., cp; I guess
we're supposed to use -R even for non-recursive traversals).
2. If we implement the historical behaviour, then -h would become a no-op
and should be left undocumented.
3. The man page suggests that without option -h, all symlinks (to files
specified in the command line?) are followed. It's not clear what
"the file" is. These bugs were introduced when -h was documented.
4. The correct interaction of -h with the other flags is not clear.
One bug was relatively harmless (select's timeout had an uninitialized
tv_usec), the other I'm not so sure.. (neglected to catch select returns
less than zero). Both of these were irrelevant on kernels with poll().
