as the old optimization did (actually does slightly better under gcc 4.0), and
simplifies the code.

anyway. This is at least less ugly than what was there before, and fixes
building all sources at once.

arpa/inet.h rather than netinet/in.h, otherwise we get warnings.

Fixes warnings about:
fdisk.c:45:1: warning: "_" redefined

md5_sha1_sum.c to convert some #ifdef CONFIG to if(ENABLE).)
|
|
For each CONFIG_SYMBOL, include/bb_config.h now has both ENABLE_SYMBOL
and USE_SYMBOL(x). ENABLE_SYMBOL is still always defined (1 or 0) so that
if(ENABLE) should optimize out when it's zero. The USE_SYMBOL(X) will only
splice in X if the symbol is defined, otherwise it'll be empty.
Thus we can convert this:
#ifdef CONFIG_ARGS
opt = bb_getopt_ulflags(argc, argv, "ab:c"
#ifdef CONFIG_THINGY
"d:"
#endif
, &bvalue
#ifdef CONFIG_THINGY
, &thingy
#endif
);
#endif
into this:
if (ENABLE_ARGS) {
opt = bb_getopt_ulflags(argc, argv, "ab:c" USE_THINGY("d:"), &bvalue
USE_THINGY(, &thingy));
}
And it should produce the same code.
Unlike the old versions in include/_usage.h, the new USE_SYMBOL(x) can handle
commas in its arguments (as shown above). (The _usage.h file is obsolete and
no longer generated.)
Nobody should need to include config.h directly anymore, bb_config.h should
define all the configuration stuff we need. Someday, the CONFIG_SYMBOL
versions should go away in favor of ENABLE_SYMBOL and USE_SYMBOL().
Thanks to vodz for the new version of bb_mkdep.c that works with function
macros.

- remove unused parameter pindex from fdisk.c, xbsd_initlabel()
|
|
- use shorter boilerplate while at it.
