C99 compatibility support went into libstdc++ in the very earliest
development snapshots (when libstdc++ was sort of less tightly
integrated to GCC).  According to the ChangeLogs, checkins from September 2000
era already introduced macro hooks for C99 math functions, with comments:

        * bits/c++config (__GLIBCPP__): Update, in the hopes of making a
        snapshot release soon.
        (_GNU_SOURCE): Define this in the header files, as ISO C99 support
        is pretty much assumed.

they were further refined into _ISOC99_SOURCE (more work in 2001) and
in the final state you can contemplate now.  The ChangeLogs and the
list archive have more information to offer to the curious
archeologist than my limited memory would recall (no, no upgrades,
thank you :-)
