libstdc++ concept checking

This page:

says "They are off by default for all versions of GCC. They can be
enabled at configure time with --enable-concept-checks. You can enable
them on a per-translation-unit basis with -D_GLIBCXX_CONCEPT_CHECKS."

I'm assuming that --enable-concept-checks is an option to use while
building libstdc++ to set the default for that library.  But does the
second sentence mean that I can enable concept checking for my own
code by defining that macro, even if libstdc++ wasn't compiled with
the option turned on?
