specific one. The GNU one is chosen when _GNU_SOURCE is defined. g++ always
defines _GNU_SOURCE on linux platforms because glibc's headers won't compile
in C++ mode without it. The GNU strerror_r doesn't always modify the buffer
which causes empty error messages on linux.
This patch changes MakeErrMsg to use the return value of strerror_r to get
the string instead of assuming the buffer will be modified, on GLIBC.

clang: error: unable to make temporary file: /etc/cc: can't make

instead of
clang: error: unable to make temporary file: /etc/cc: can't make
unique filenamePermission denied
for example.
Also, audited the uses of MakeErrMsg to make the prefix strings
consistent (not end with newline/punctuation/space/": ").

llvm::sys::getOS{Name,Version}.
Right now the implementation just derives from LLVM_HOSTTRIPLE (which
is wrong, but it doesn't look like we have a define for the target
triple). Ideally this routine would actually be able to compute the
triple for targets we care about.

where the handle bus errors) also, clear the signal mask so that the

RemoveDirectoryOnSignal as it is dead and has never had clients.
Change PrintStackTraceOnErrorSignal to be implemented in terms of

I updated the Win32 versions of these APIs, but can't test them.
If there are any problems, I'd be happy to fix them as well.

PRIxPTR with a cast to uintptr_t would work here, but that requires
inconvenient build-system changes. %lu works on all current and
foreseable future hosts.

This fix is applied identically to the win32 code as well, but that is
untested.

functional changes. Win32 code is untested, but should work fine.
In the unix variant, rename RedirectFD to RedirectIO and let that function
handle empty and null paths instead of doing that in the caller 3 times. This
is the same as win32 already does it.
In the win32 variant, use Path::isEmpty() instead of checking the resulting
c_str() manually. This is the same as unix already does it.
