The AC_CHECK_HEADER macro was used instead of AC_CHECK_HEADERS. The former does
not automatically add a #define to the configure variables while the latter
does. Consequently, the HAVE_PTHREAD_H symbol was not defined which caused the
Mutex.cpp file to compile to an empty implementation.

JITer (short path is added for darwin). This is needed to properly JIT llvm-gcc-4.2-built
binaries, since cxa_atexit is enabled by default on much more targets.

stands a chance of being compiled with a non C99 C compiler. The default
is enabled so you must specifically disable this feature if you want the
CBE output compiled with an older C compiler.

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 configure checks for setjmp/longjmp for Chris. I can't believe this easy
PR has been outstanding for so long. If I don't get to something, please
remind me! :)

are available. These libraries are used in lib/System and should be
included on the link line or if not available generate an error when
building lib/System.

These patches make threading optional in LLVM. The configuration scripts are now
modified to accept a --disable-threads switch. If this is used, the Mutex class
will be implemented with all functions as no-op. Furthermore, linking against
libpthread will not be done. Finally, the ParallelJIT example needs libpthread
so its makefile was changed to always add -lpthread to the link line.

Previously the script assumed the version number was the last field, now
it assumes it is the first sequence of digits.

we actually get the path and not $GRAPHVIZ as the value.
* Add a #define for the gv program (HAVE_GV) and its value LLVM_PATH_GV.

GRAPHVIZ will contain the path to the program if its found (or "echo Graphviz"
if not) and the #define HAVE_GRAPHVIZ will be defined if its found.

enhancement for ffs, ffsl, and ffsll optimizations. We can't do the opt
unless we also have the at least ffsll function. Notably SVR4 doesn't.

* Add CAN_DLOPEN_SELF so we can determine if dlopen(0) will open the
program or not.
* Correct a warning messages to be a little more specific on what it checks

* Add check to determine if /dev/zero is needed for allocating RWX memory.

* Make sure all headers used by lib/System have checks
* Use "standard" autoconf checks for certain problematic headers
For PR432:
* Resurrect --with-llvmgccdir so a specific llvm-gcc/llvm-g++ installation
can be specified.

Create new variables LLVM_ON_UNIX and LLVM_ON_WIN32 so we can start getting
rid of reliance upon a symbolic link to switch implementations in lib/System
