// This is a hack around not having either pre-compiled headers or
// export compilation. If defined, the io, string, and valarray
// headers will include all the necessary bits. If not defined, the
// implementation optimizes the headers for the most commonly-used
// types. For the io library, this means that larger, out-of-line
// member functions are only declared, and definitions are not parsed
// by the compiler, but instead instantiated into the library binary.

// Define this to permit user-level control of the expansion of string
// buffers (via a fn pointer), see basic_string.* for more.

// Map gthr.h abstraction to that required for STL.  Do not key off of
// __GTHREADS at this point since we haven't seen the correct symbol
// yet, instead setup so that include/bits/stl_threads.h will know to

// that gthr.h may well map to gthr-single.h which is a correct way to
// express no threads support in gcc.  As a user, do not define
// _NOTHREADS without consideration of the consequences (e.g. it is an
// internal ABI change).
