Commit f540ea64 authored by Uwe Bonnes's avatar Uwe Bonnes Committed by Alexandre Julliard

Rough implementation of _O_TEXT/_O_BINARY translation by doing single

byte read/writes in _O_TEXT mode and CR/LR handling. fput/getwc must read multibyte characters in _O_TEXT. Added test cases for _O_TEXT/_O_BINARY file handling and fgetws.
