070c42f311 glibc has two versions of strerror_r, a standards compliant one and a GNU
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.

4cdc44c82c Fix g++-4.4.0 warning, it was causing llvm-nm to fail on wrapped BC files:
Path.cpp:59: warning: case label value exceeds maximum value for type
magic[0] is a (signed) char, but some case values are unsigned (e.g. 0xde).
When magic[0] was 0xde, the switch has taken the default branch instead of case
0xde branch.
Apparently this was the behaviour with older versions of gcc too, but not with g++.
Now g++-4.4 behaves as gcc, and ignores unsigned case values out of range signed
range.

a7f2a9e69f Make Unix.h:MakeErrMsg separate the prefix and errno string, so we get:
clang: error: unable to make temporary file: /etc/cc: can't make
  unique filename: Permission denied

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/": ").

be46c79501 Add llvm::sys::getHostTriple and remove
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.

- Make type declarations match the struct/class keyword of the definition.
 - Move AddSignalHandler into the namespace where it belongs.
 - Correctly call functions from template base.
 - Some other small changes.
With this patch, LLVM and Clang should build properly and with far less noise under VS2008.

Cleanup some warning.

Remark: when struct/class are declared differently than they are defined, this make problem for VC++ since it seems to mangle class differently that struct. These error are very hard to understand and find. So please, try to keep your definition/declaration in sync.

Only tested with VS2008. hope it does not break anything. feel free to revert.
