2) The check_cc macros should probably all have the same number of arguments.
3) Move the -Werror into the gcc 4.0 on i386 test, because gcc 4.1 is broken
and produces warnings for things that provably aren't incorrect.
In other news it would be nice if our check_ld macro actually did something,
and why does or makefile do all the check_cc calls, then call itself as if
it's building out of tree, then do all the check_cc calls again?
Adds "Enable getopt long" under "General options", default y.
Send patches to fix getopt_ulflags and run_parts.c if you turn this off..
See http://busybox.net/lists/busybox/2006-May/021828.html for a start to run-parts
- rename check_gcc to check_cc and pass the CC to use as arg#1; peruse check_cc for HOSTCFLAGS
- add and use check_strip
- add checks for {,no-}whole-archive and {start,end}-group LD flags
(with O=directory), and reverting them fixes building out of tree. I'd be
happy to fix them up instead of reverting them if I had the foggiest idea
what they were trying to do, but I don't, and this at least gets building
out of tree working again...
the lib (due to bug in gcc; see comment.)
I would have run the testsuite to check if everything is still behaving, but
unfortunately i cannot run the testsuite anymore: it just sits there and does
nothing even with a pristine checkout and an old gcc.

I've just corrected that wrong double-printing.
Anyway. with gcc-4.1-HEAD from earlier today, we now have for
defconfig+ COMPILE_AT_ONCE:

values for 4.0.2 just added for reference..
$(srcdir) can't bind early since it's set to a different value in each subdir.
If it binds early, it's blank, hence an empty -I which eats the next option
as a directory to look for #include files in.
So CFLAGS has to bind late, but the check_gcc stuff should only get run once.
I added a "make V=2" mode to show when check_gcc gets run, and turned WARNINGS
into a CFLAGS line since it was always getting added anyway.
e.g. archival/uncompress.c wrongly includes libbb.h instead of busybox.h
decompress_bunzip2.c,open_transformer.c don't include the proper "unarchive.h"
etc, etc.
- don't overwrite objects in the archive. Affected applets with name-clash
mostly vs. libbb:
iplink_main
iproute_main
iptunnel_main
login_main
run_parts_main
