152b2bc046 This is horrible. Split the difference, and declare 'environ' on all non-Darwin 
platforms to unbreak the darwin and linux builds. The BSD folks should feel
free to change the #if, if this breaks them.

22b58ac393 make Program::Execute use posix_spawn on systems that support it, 
as it is more efficient than fork/exec.

Thanks to Eric for adding the autoconf check.  It would be nice if
a cmake guru could add a cmake check for posix_spawn as well.

got the bar value, not "bar".

58964f4bee Fix a false-positive memory leak in code using RemoveFileOnSignal(). Because 
libstdc++'s std::string class points to the interior of an allocation, valgrind
reports strings still alive at program termination as possible leaks.  I didn't
use a ManagedStatic for this because System can't depend on Support.

46115632ba Make clang bootstrap happier on OSX 10.5 by reducing the number of headers 
included when using global symbols to ask the linker for the addresses of
various functions.  One of the symbols was actually getting declared by a
header included in DynamicLibrary.cpp, which conflicted with the "extern void*"
declaration in SearchForAddressOfSpecialSymbol().

46925cc515 Fix TimeValue::now() on Unix. 
TimeValue()::now().toEpochTime() is supposed to be the same as time(),
but it wasn't, because toEpoch subtracted PosixZeroTime, but now()
didn't add PosixZeroTime!
Add a unittest to check this works.

9f306d1b18 Move the extern symbol declarations outside of 
DynamicLibrary::SearchForAddressOfSymbol and force them to have "C"
linkage. 

Interestingly, GCC treats the block-scoped "extern" declarations we
previously had as if they were extern "C" declarations (or, at least,
were in the global namespace), so that GCC bug papered over this LLVM
bug. Clang and EDG get the linkage correct; this new variant seems to
work for both GCC and Clang.

388463f7c4 Add "generic" fallback. 
gcc warned that the function may not have a return value, indeed
for non-intel and non-amd X86 CPUs it is right (VIA, etc.).

57fe66cf5b Using _MSC_VER there was wrong, better just use the already existing ifdefs for 
x86 CPU detection for the X86 getHostCPUName too, and create a simple
getHostCPUName that returns "generic" for all else.

6c46ee4a5b Enable CPU detection when using MS VS 2k8 too. 
MSVS2k8 doesn't define __i386__, hence all the CPU detection code was disabled.

435a9894a7 This patch ensures that Path::GetMainExecutable is able to handle the 
case where realpath() fails. When this occurs we segfault trying to
create a std::string from a NULL pointer.
