* lib/_cygwin_S_IEXEC.c: Remove "const" from globals or they never seem to be

defined.  Wrap definitions in extern "C".  Include winsup.h to assure proper
definitions.
* dcrt0.cc (dll_crt0_1): Call stdio_init after premain run so that binmode.o,
etc., will control default stdio settings.
* dtable.cc (dtable::init_std_file_from_handle): Allow __fmode to force
binmode/textmode settings.  Default pipes to binmode.
