Subject: gcc -pipe. Once again :-)

I modified egsc's pexecute.c to use common code for both cygwin and mingw 
versions. Also I made a change to avoid read end of pipe inheritance 
problem we discussed some time ago.

pexecute.c	Cygwin-specific code removed;
		(pexecute): create a pipe with non-inheritable handles, call spawn 
functions
		without underscores for cygwin32;
		(pwait): just return wait(status) for cygwin32.

To support this changes I had to modify winsup sources :-) New 
MSVC-compatible _pipe() call is implemented.

cygwin.din	_pipe export is no longer an alias for pipe.

fhandler.cc	(fhandler_make_pipe): new parameters psize and mode - pipe's 
buffer size and
		open mode; create pipe's handles noninherittable if O_NOINHERIT mode is 
set,
		use psize argument in CreatePipe() call, set pipe's mode to text if 
O_TEXT
		flag is set.

pipe.cc	(pipe): call fhandler_make_pipe with a default buffer size and 
_fmode.
		(_pipe): new.

winsup.h	prototype for fhandler_make_pipe changed.

include/fcntl.h	O_NOINHERIT define added.
