have to provide the macros.
In addition, several libstdc++-v3 source files unconditionally define the macro
@code{_POSIX_SOURCE}. On many systems, defining this macro causes large
portions of the C library header files to be eliminated at preprocessing
time. Therefore, you may have to @code{#undef} this macro, or define
other macros (like @code{_LARGEFILE_SOURCE} or @code{__EXTENSIONS__}).
You won't know what macros to define or undefine at this point; you'll
have to try compiling the library and seeing what goes wrong. If you
see errors about calling functions that have not been declared, look in
your C library headers to see if the functions are declared there, and
then figure out what macros you should but in @file{bits/os_defines.h}
to make these declarations available.
