This needs a second pass to:
+ add bb_daemon(unsigned char no_chdir, unsigned char no_close, const char*flag)
+ eventually globally export argc and argv, so we don't need to pass it to
bb_daemon().
http://www.opengroup.org/onlinepubs/009695399/functions/waitpid.html suggests
that we need not specify a status if we don't want, and we don't.
"If wait() or waitpid() return because the status of a child process is available, these functions shall return a value equal to the process ID of the child process. In this case, if the value of the argument stat_loc is not a null pointer, information shall be stored in the location pointed to by stat_loc. "

- add second argument to waitfor(*action,pid); if action==NULL then use pid tor
wait for. If an action was given, we wait for the action to finish just as
before. In run() remove second and third occurance of the same functionality
the waitfor() call now provides.
Adjust the former only caller of waitfor accordingly.
PS: Not using waitfor but creating a second function used a few bytes more than
simply extending and reusing waitfor.

bloatcheck is completely useless as it sees -79 for this, which is bogus.
Adds "Enable getopt long" under "General options", default y.
Send patches to fix getopt_ulflags and run_parts.c if you turn this off..

- 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
- add ATTRIBUTE_ALWAYS_INLINE, endian handling for DEC UNIX, some more
compiler dependent defines to platform.h
- add conditional bb_setpgrp define to platform.h
- remove superfluous specifying args from "#define fdprintf dprintf"
- 'function fn_name\n{' breaks on older FreeBSD default shells, so use the more
widely supported 'fn_name () {'. This needs more fixing..
- test for integers ought to use the proper operators
- test for strings ought to use quoting of the strings to be fair to strange
implementations of test(1)
- make sure not to ignore return-codes != 0 from commands; Some shells exit
immediately on this (much like explicitely requesting set -e in e.g. bash)
TODO:
*) Some older shells do not allow a space after the test-condition in an "if"
statement. This doesn't work:
if [ $status -ne 0 ] ; then
as opposed to this:
if [ $status -ne 0 ]; then
or this
if [ $status -ne 0 ]
then
*) strict spacing between commands. In some shells you have to say:
foo ; bar ; baz
The affected shells barf on stuff like ommitting the space, so this doesn't
work:
foo; bar ;baz
*) $() vs. ``
The former isn't really portable as opposed to the latter.
*) fix frong assumption that the testsuite is run from the source-dir.
This is a complete misconception and renders the testsuite completely useless.
That said, i note that IMO a test-harness ought to do it's best to work in
a wide variety of environments, everything else defeats it's purpose.
- flag .depend as .NOTPARALLEL to workaround bug in make-3.80 and make-3.81
Some more details on the second workaround (i.e. kludge):
make-3.80 silently fails, while make-3.81 is at least self-conscious enough to
admit:
include/usage_compressed.h: .config scripts/usage
# Implicit rule search has not been done.
# File does not exist.
# File has not been updated.
# Dependencies commands running (THIS IS A BUG).
# commands to execute (from `/home/cow/src/bb2/Makefile', line 430):
$(Q)$(SHELL) $(top_srcdir)/scripts/usage_compressed "$(top_builddir)/scripts" > $@
I'm giving up on trying to run the rest of the prerequisites of .depend in
parallel and just (try to) indicate that the prerequisites of .depend are
not to be run in parallel.
While this makes `make distclean defconfig;make -j´ work for me, it is not a
real -- longterm -- solution; FIXME
SIGIOT is not defined in any standard i can find and it seems to be
useless (alias for SIGABRT) on linux. i put it in #ifdef but it's
probably best just to remove it and cut down the size a bit.

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.
