to use -Wfoo instead of -Wno-foo. This works around a bug in some versions of
gcc, where it will silently accept an unknown -Wno-foo option, but will
generate an error for a compile which uses -Wno-foo if that compile also
triggers any warnings.

gets placed inside a main function, and should not itself be a main
function. This is silently hidden in GCC-hosted builds because the
inner main looks like a nested function declaration, which GCC supports.
In builds with compilers which do not support nested functions (by default),
this was causing an error, which caused these autoconf checks to fail,
leaving their options disabled.
This fixes test/Feature/load_module.ll on x86_64-unknown-linux-gnu
llvm-gcc selfhost builds, among other things.
This also includes a regenerated configure, as the diff is small and telling.

use of that option with it. This eliminates an imprecise "Linux"
test, and should help support old versions of gold.

HAVE_{BI,STD,FWD}_ITERATOR and HAVE_NAMESPACES were not used in the code.
bison and flex are no longer used.
CAN_DLOPEN_SELF was never used either.
AC_PROG_LIBTOOL is not needed since we don't use libtool, we only need the
libltdl checks for dlopen.
Add check for AR, it used to be done by AC_PROG_LIBTOOL.
AC_TYPE_SIGNAL is deprecated, follow autoupdate's suggestion and replace with
void.
Remove unused m4 files.
Configure can now be generated using autoconf 2.65 too, without any warnings!

with a 64-bit kernel, which confuses LLVM. Make LLVM double-check this by
checking which defines the system gcc actually sets.

that all the Makefiles changed mode.
Fix this by tellint install-sh to chmod
only to 0644, these are not executable files after all!

plain wrong since $module was never defined so we always get .so which is
broken on Darwin. Just force it to .dylib.

Demote check for bison from error to warning and make sure that the
makefile can handle an empty definition for BISON variable.

Fix problem setting the USE_{program} variable. It should be set to a
Makefile variable definition line, not just "1". Problem noted by
Kenneth Hoste.

Fix problem noticed by Kenneth Hoste. The wrong name for a variable was
being set and subsequently uses of the correct name were empty.

Update ltld.[ch] to version 1.5.22.
Correct the notes about updating these tools (autoconf/README.TXT)
Add configure options for getting the correct option for including a whole
archive when linking.

Add a macro for getting the build host extension for executable. Patch
