* win/configure: Regen.

	* win/tcl.m4 (SC_CONFIG_CFLAGS): Check for bug in Cygwin version
	of windres and work around that case by passing a POSIX path
	instead of a Windows native path. One can't always pass a POSIX
	path because the mingw native toolchain accepts only Windows
	native paths. (dejong)
