[PATCH] [libc++] Check the support of default function template args.

[Logan Chien]

Hi Howard,

I am doing some experiment to replace stlport with libc++ in the Android
platform, which does not have libstdc++.  Although I can compile the libc++
library itself with clang, I can't build the world with clang at the
moment.  Thus, I wish to make the C++98/03 headers compatible with g++, so
that I can include them without problems.

Sincerely,
Logan
