Hello,

 This change:

2006-11-30  Christopher Faylor  <cgf@timesys.com>

	* win/tclWinPipe.c (TclpCreateProcess): Call cygwin-specific routine to
	set up windows environment.

broke building on versions of Cygwin predating 1.15.20.  The 
CW_SYNC_WINENV internal call was not previously available.  Here is a fix.

2007-05-10  Maciej W. Rozycki  <macro@mips.com>

	* win/tclWinPipe.c (TclpCreateProcess): Only use CW_SYNC_WINENV
	for Cygwin 1.15.20+.

 OK to apply?

  Maciej
