Hi Jonathan,
Today I build gcc5 and looked at the config.h contained in
libstdc++-v3's build directory and none of those variables are enabled.

The code that is patched doesn't seem to do anything.  I grepped the
entire build directory for "libstdcxx_time" and got no results.

I don't have "--enable-libstdcxx-time" set as a configure argument.  So
I am thinking somehow this configuration check got skipped completely.
