Implements death tests on Windows (by Vlad Losev); enables POSIX regex on Mac and Cygwin; fixes build issue on some Linux versions due to PATH_MAX.

Updates the definitions of GTEST_HAS_EXCEPTIONS and GTEST_HAS_STD_STRING to be C++ standard compliant.

Adds tests for EXPECT_FATAL_FAILURE and reduces the golden file bloat (by Zhanyong Wan).  Fixes more warnings on Windows (by Vlad Losev).

Fixes the bug where the XML output path is affected by test changing the current directory.  By Stefan Weigand.

Improves compatibility with cygwin by making the definition of GTEST_HAS_GLOBAL_WSTRING correct on this platform.

allows other projects to easily leverage an installation or
un-installed build of Google Test from their project's Autoconf
script. This re-work specifically introduces the ability to provide a
path as an argument to the resulting configure script option which can
specify either an installation prefix or a build directory for Google
Test.

This change also makes a small portability tweak by using ``s instead
of $() for command expansion.
