2010-07-04 Martin Sebor <se...@apache.org>
STDCXX-1049
* include/fstream (basic_filebuf::basic_filebuf, basic_filebuf::open,
basic_filebuf::fd, basic_filebuf::attach, basic_filebuf::detach):
Guarded POSIX extensions using _RWSTD_NO_NATIVE_IO.
(basic_ifstream, basic_ofstream, basic_fstream): Same.
* src/iostream.cpp (<unistd.h>): Included only if _RWSTD_NO_NATIVE_IO
is not defined.
(_RWSTD_DEFINE_STREAM_OBJECT): Modified to use stdin, stdout, and
stderr when _RWSTD_NO_NATIVE_IO is defined, otherwise STDIN_FILENO,
STDOUT_FILENO, STDERR_FILENO.
(ios_base::Init::Init): Adjusted.
* tests/iostream/27.filebuf.cpp (test_ctors, test_attach): Avoided
testing POSIX extensions above when _RWSTD_NO_NATIVE_IO is defined.
* tests/regress/27.filebuf.members.stdcxx-308.cpp: Same.
