7abb8df743 Apply a patch from Kees van Reeuwijk to add support for Minix. 
Minix apparently doesn't like double-slash separators, and there's
no apparent need for them here.

3bca7bf84d System: Fix getMagicNumber on windows. 
getMagicNumber was treating the _binary_ data it read in as a
null terminated string. This resulted in the std::string
calculating the length, and causing an assert in other code that
assumed that the length it passed was the same as the length of
the string it would get back.

5cb73a9fb8 Don't cast Win32 FILETIME structs to int64. Patch by Dimitry Andric! 
According to the Microsoft documentation here:
http://msdn.microsoft.com/en-us/library/ms724284%28VS.85%29.aspx

this cast used in lib/System/Win32/Path.inc:

__int64 ft = *reinterpret_cast<__int64*>(&fi.ftLastWriteTime);

should not be done.  The documentation says: "Do not cast a pointer to a
FILETIME structure to either a ULARGE_INTEGER* or __int64* value because
it can cause alignment faults on 64-bit Windows."

093ad188e7 CrashRecovery/Darwin: On Darwin, raise sends a signal to the main thread instead 
of the current thread. This has the unfortunate effect that assert() and abort()
will end up bypassing our crash recovery attempts. We work around this for
anything in the same linkage unit by just defining our own versions of the
assert handler and abort.

b049874698 Factor out the handler work from SignalHandler into a helper function, 
and change llvm::sys::RunInterruptHandlers to call that function directly
instead of calling SignalHandler, because the rest of SignalHandler
invokes side effects which aren't appropriate, including raising the
signal.

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.

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.
