577905f1e4 Revert duplicate patch. 
I don't know why patch decided to apply this even though it was already in
the tree.  I thought the other hunks failed because they were totally
unrelated leakage from Bernhard's tree (which they are; was the a reason
for bundling them in with this fix?  Do they have something to do with
the GCC 2.95 fix?  I suspect they prevent me from backporting this
patch to 1.2.2 because the header consolidation into libbb.h hadn't
been done yet, and no I'm not fixing it up: if that's the case then
this patch won't be in 1.2.2 due to extraneous changes bundled with it that
prevent a clean backport without rolling a new patch).

b5f50ea344 - small trivia to be gentle to gcc-2.95.x which had no va_copy but only __va_copy. 2006-09-12 13:27:55 +00:00
Rob Landley
b988462d3e Ok, features.h already defines _OPEN_SOURCE (and complains if it's already 
defined), yet it's not doing it for scripts/individual for some reason.
(I hate fighting with header files.)

519d7df930 Another whack at scripts/individual. Now builds 212 applets. 2006-08-09 20:56:23 +00:00

e3781b7312 Add shared subtree support, suggested by Vladimir Dronnikov. Also break out a 
few new (unfinished) config options, which I intend to make hidden (but
enabled) when CONFIG_NITPICK is disabled.  Getting the .config infrastructure
to do that is non-obvious, it seems...

148734df99 We came up with our own names for ATTRIBUTE_*, so why check if they're already 
#defined?  Also remove a check for a gcc version older than RH9 (if non-linux
needs that #define they can put it in their section.)

22d26fc6ae Patch from Yann Morin to put BLKGETSIZE64 in platform.h had rather a lot of 
fallout due to the #include <sys/mount.h>.  Removed that #include from various
applets and fixed up those that were unhappy when that #include was made
because they'd block copied stuff out of it.  (Sigh.)

8fc32d9326 Shaun Jackman pointed out that KERNEL_VERSION() is used without guards, so 
defining it in a guard is silly.

Kjellerstedt.

bba7f08d27 Add SWAP_LE?? and SWAP_BE?? macros, and make things use them. Converts values 
to/from little endian or big endian, which is a NOP if that's what the current
platform already is.

15d20a03d6 Remove _() and N_() from platform.h. #define them as NOP macros in the two 
files still using them.  I didn't remove them from e2fsck.c to avoid stomping
pending cleanup patches from Garrett, and I didn't bother to remove them from
fdisk.c because that entire file needs to be rewritten from scratch.

8fba99f35e Move portability stuff to platform.h, and clean up adjtimex.c a bit while

e00fc16aaa - move libc checks from busybox.h to platform.h

  compiler dependent defines to platform.h

a389651115 Remove bb_strlen() in favor of -fno-builtin-strlen. Saves as many bytes 
as the old optimization did (actually does slightly better under gcc 4.0), and
simplifies the code.
