Drop the pipe() macro. Defining macros outside of its namespace that look

2007-05-13  Tor Lillqvist  <tml@novell.com>

	* glib/gwin32.h: Drop the pipe() macro. Defining macros outside of
	its namespace that look like POSIX functions is not GLib's
	business in my opinion. This means pipe()-using code that has
	relied on this definition will need changing to call _pipe() on
	Windows, and make the decision itself on what size pipe buffer to
	use, and whether to use text or binary mode, and whether the pipe
	handles should be inheritable or not.

	* glib/gspawn-win32.c (make_pipe): Use _pipe() instead of pipe().
