PATCH: _open_osfhandle() has incorrect default for text/binary mode

[Adam Gundy]

The _open_osfhandle() function in MSVCRT is expected to take the absence
of either _O_TEXT or _O_BINARY to mean _O_BINARY. Currently it defaults to
_O_TEXT.

An example of this is MFC's CStdioFile::Open in binary mode - it passes flags
of 0 when it wants to write a binary file - under WINE we do text mode conversions!

The attached patch ensures that _O_BINARY is set if neither is set in the passed-in
flags.

Real Programmers don't comment their code. If it was hard to write,
it should be hard to read, and even harder to modify.
These are all my own opinions.
