Created an attachment (id=3306)
 --> (http://llvm.org/bugs/attachment.cgi?id=3306)
Log of make demonstrating the failure.

I'm running on Windows 7 RC (64-bit) using Cygwin. I'm trying to build the gcc
front-end and get a failure building crtbegin.o -- but there is no error
message.

I've attached a log of the stdout/stderr from the make.

So there are two bugs:

1. xgxx fails silently
2. xgxx fails to build crtbegin.o.

Note: Source trees for llvm and llvm-gcc were pulled via SVN from the
RELEASE_25 tag. I built llvm just fine (using a build target of tools-only) and
installed it. The config and make of llvm-gcc worked without any problem up to
this failure.

Note2: This version info for xgcc and gcc might be helpful:
