indeed a good change, I shouldn't have made it after testing
with the -DNOCLEAN buildworld. There are far too many users
of this misfeature under sys/boot/. I will reapply the change
after I fix these.
This change has been tested with the clean buildworld.
Make the defined(SRCS) case similar to the !defined(SRCS)
case - only define ${PROG}: ${OBJS} if the ${PROG} target
does not exist. This has only one precedence in the entire
source tree, usr.bin/doscmd, and its Makefile is horribly
broken. I will temporarily unconnect it from build until
I'm working on the fix.
the .PATH (but not in the ${.OBJDIR}) would result in a leak of
the ${OBJS}: ${SRCS:M*.h} dependency hint.
Spotted by: fixing the broken gnu/usr.bin/cc/cc1obj build
MFC after: 1 day
to pick up the correct cross-tools (the compiler executables and binutils)
and special linker files (crt*.o). This is now controlled by a single knob,
TOOLS_PREFIX, when building cross-tools.
Fixed regression in Makefile.inc1,v 1.203 (-nostdinc). This clobbered target
architecture's CFLAGS with building host's CPUTYPE setting in /etc/make.conf,
and had a nice but nasty side effect of exposing some (normally hidden) bugs
in system headers.
(Attempt to move the "-nostdinc -I..." part of CFLAGS into the new CINCLUDES
(modeled after a similar CXXINCLUDES) eventually failed because hard-coding
${WORLDTMP}/usr/include to be the first in the include list does not always
work, e.g. lib/libbind.)
Compensate the -nostdinc removal by making cpp(1) built in the cross-tools
stage to not look for <> header files in the building host's /usr/include
(already committed as gnu/usr.bin/cc/cc_tools/freebsd-native.h, revisions
1.10-1.12, STANDARD_INCLUDE_DIR).

(Disabling the use of GCC_INCLUDE_DIR in the FREEBSD_NATIVE case would fix
the duplicate above.)
Get rid of the (now unneeded) -I${DESTDIR}/usr/include magic in bsd.prog.mk
and bsd.lib.mk. Finish the removal of LDDESTDIR in bsd.lib.mk,v 1.55 -- we
no longer have users of it.
The required changes to gcc were already committed as contrib/gcc.295/gcc.c,
revisions 1.23 and 1.24.
Basically, this allows for the changes above plus makes gcc(1) persistent
about path configuration, whether it's configured as a native or a cross
compiler:

libraries a little by not passing all of ${CFLAGS} to lint. Pass
only options matching -[DIU]*. The important -nostdinc option can't
be passed like I first thought because lint misinterprets as
"-n -o stdinc". The unimportant -B* option can't be passed because
lint doesn't support it. Otherwise, we pass the same options as
to mkdep, exept for a bug in the latter: -U* is not passed. All
this depends on option args not being separated from option flags
by a space.
to avoid polluting sys.mk. This directive controls the addition of
compiler warning flags to CFLAGS in a relatively compiler-neutral manner.
The idea is that WARNS can be set in Makefile.inc or in individual
Makefiles as they become clean, to prevent the introduction of new
warnings in the code. -Werror is added by default
manual section. If, for example, MANSECT is set to 8, the default
MAN1=${PROG}.1 feature of bsd.prog.mk becomes MAN8=${PROG}.8.
Useful for games, libexec, sbin and usr.sbin subtrees.

Specifically intended for removing -fschg ("INSTALLFLAGS_EDIT=:S/schg/uchg/")
this makes the NOFSCHG flag redundant. NOFSCHG will still be honoured by
bsd.lib.mk but is valid for buildworld only. NOFSCHG is still implemented in
the old way (ie. _not_ ".if NOFSCHG then { INSTALLFLAGS_EDIT+=:S/schg/,/ }"
to emphasize the fact that NOFSCHG is only supported in a limited
fashion and for buildworld.
The interface and implementation are such that future use of flags such
as sappnd can also be easily removed or altered (perhaps to uappnd).

/usr/sbin/sysctl -> ${DESTDIR}/sbin/sysctl in some versions of 2.2,
and this link was broken if DESTDIR was set.
Added a SYMLINKS macro. This works the same as LINKS, except it
creates symlinks and the linked-to pathname may be relative. This
is more flexible than LN_FLAGS, since it supports installing
symlinks independently of hard links.
Use `ln -f[s] ...' instead of `rm -f ...; ln [-s] ...' for LINKS and
SYMLINKS. This is equivalent if the target is neither a directory nor
a symlink to a directory.

when certain .mk files include other .mk files. This will remove the
need for multiple include protection in some other makefiles around the
tree (and helps some elf conditionals).
Notes:
- We no longer use -fgnu-runtime in bsd.lib.mk, since it is the default
and bsd.lib.mk is the wrong place to override it.
- Gnu C doesn't have a special compiler driver for Objective C like it
does for C++. The defaults are suitable for Gnu C. Use `OBJCLIBS='
in /etc/make.conf for POC.
that want a y.tab.h file. This want must be specified by putting y.tab.h
in SRCS (and defaulting to or putting -d in YFLAGS). This only works if
there is only one yacc parser, of course. One improvement: copy y.tab.c
to foo.c instead of renaming it, so that `#line...y.tab.c' statements in
it refer to an existing file.
Regress to not generating explicit rules for .l and .y sources containing
slashes. This case is unusual and hard to handle properly.
Don't generate an unused dependency when -d is not in YFLAGS.
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.
