@defvr Macro _ISOC99_SOURCE
@standards{GNU, (none)}
Until the revised @w{ISO C} standard is widely adopted the new features
are not automatically enabled. @Theglibc{} nevertheless has a complete
implementation of the new standard and to enable the new features the
macro @code{_ISOC99_SOURCE} should be defined.
If this macro is defined, features from ISO C99 are included. Since
these features are included by default, this macro is mostly relevant
when the compiler uses an earlier language version.
