This is simpler, and is easy to do now that make(1) supports substituting
regexps. Fixed missing '$' anchor in the regexp. Use less cryptic names
for temporary variables.

symbols from object files has bitrotted over the last
thirteen years, and it now does more harm than good.
An attempt to work around the problems caused by using
ld(1) for stripping was to pass LDFLAGS to the ld(1)
command, but this was not right either as ${LDFLAGS}
should, by design, be used with cc(1) and not ld(1).
One of the proposed solutions was to use the objcopy(1)
utility to do the strip work, and the other would be to
use strip(1), but Bruce Evans suggested not stripping
any symbols at all. This works by leaving the grunt
work to the final strip(1) command (when installing the
binary).

it gets the job done for the /rescue case.

is that libc is not c99 clean internally.

This should be removed when we update to gcc 3.3 or the bug is otherwise fixed.

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.
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.
