Yes. However, you need the attached patch as well. I cannot pass "-std
strict_ansi" through in CXXFLAGS because there is an assumption the C
and C++ compilers accept the same arguments. This patch fixes that.
I've left WERROR_CFLAGS in because I'll hope that fails for any
non-GNU C++ compiler.

With this patch, all tests pass on Tru64 UNIX with
CXXFLAGS="-std strict_ansi".
