9820f41cd3 Don't use -pedantic unless we also set -std of some kind. 2003-05-05 21:13:32 +00:00

77695b344b Add a mechanism to allow Makefiles to specify the particular C dialect
in which the source code is written.  This is controlled by the CSTD
variable, which can have one of the following values:

  - "k&r"		=> -traditional
  - "c89" or "c90"	=> -std=iso9899:1990
  - "c94" or "c95"	=> -std=iso9899:199409
  - "c99"		=> -std=iso9899:1999

The corresponding option is added to CFLAGS regardless of WARNS level.
This also removes -ansi from WARNS level 6, but adds -Wno-long-long to
work around a weird gcc bug (-ansi, which is supposedly equivalent to
-std=iso9899:1990, seems to turn long long warnings off instead of on)

If CSTD is undefined, CFLAGS are unchanged except for the -ansi /
-Wno-long-long change mentioned above for WARNS level 6.

30aaff1192 Migrate to a new way of dealing with building from old revisions of
FreeBSD.  This method attempts to centralize all the necessary hacks
or work arounds in one of two places in the tree (src/Makefile.inc1
and src/tools/build).  We build a small compatibility library
(libbuild.a) as well as selectively installing necessary include
files.  We then include this directory when building host binaries.

This removes all the past release compatibilty hacks from various
places in the tree.  We still build on tip of stable and current.  I
will work with those that want to support more, although I anticipate
it will just work.

Many thanks to ru@, obrien@ and jhb@ for providing valuable input at
various stage of implementation, as well as for working together to
positively effect a change for the better.

0e80a2f601 -Wall implies -Wuninitialized if -O is also in effect.
-Wuninitialized does not work without -O.

This fixes the ${WARNS} > 4 compilations with -O0.

effd19ed24 Enable cpp(1) warnings in system headers. GCC is oriented on
glibc which is externally maintained, so GCC ships with these
warnings turned off by default.  This is also consistent with
the src/contrib/gcc/c-lex.c,v 1.2 change.

89d1cbc7aa Add WARNS levels 5 and 6:
5 gives us -Wuninitialized rather than -Wno-uninitialized
6 gives us full BDECFLAGS

7cf143f761 FreeBSD prior to 4.5-RELEASE and older versions of 5.0-CURRENT do not
have the __FBSDID() macro in <sys/cdefs.h>.  Fix this once and for all
for tools that need to be bootstrapped.

3ad920fe65 Put -Wno-uninitialized at the end of the warns flags as it may be enabeled
by several flags (in this case -W and -Wall).

328c7f1d7d Add some granularity to the WARNS levels.
1:  add -Werror
2:  -Wall [only], as this is the most used warnings setting by developers
3:  our old `1'
4:  our old `2'

d510ecb42b Bring in the WARNS directive from NetBSD, localized in a new bsd.sys.mk
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
