	* generic/tclInt.decls        Revert some cygwin-related signature changes from
	* generic/tclIntPlatDecls.h   [835f8e1e9d] (2010-01-22). They were an attempt to
	* win/tclWinError.c           make the cygwin port compile again, but since cygwin
	                              is based on unix this serves no purpose any more.
	* win/tclWinSerial.c:         Use EAGAIN in stead of EWOULDBLOCK, because in
	* win/tclWinSock.c:           VS10+ the value of EWOULDBLOCK is no longer the
	                              same as EAGAIN
	* unix/Makefile.in            Add tclWinError.c to the CYGWIN build.
	* unix/tcl.m4
	* unix/configure

2012-03-20  Jan Nijtmans  <[email protected]>

	* generic/tcl.decls:           [Bug 3508771] load tclreg.dll in cygwin tclsh
	* generic/tclInt.decls:        Implement TclWinGetPlatformId, Tcl_WinUtfToTChar,
	* generic/tclIntPlatDecls.h:   Tcl_WinTCharToUtf (and a dummy TclWinCPUID) for 
	* generic/tclPlatDecls.h:      Cygwin, so win32 extensions using those can be
	* generic/tclStubInit.c:       loaded in the cygwin version of tclsh.
