* Makefile.in:  Install gdbtcl dir instead of gdbtk.tcl.

	* gdbtk.c: Added some ifdefs for Windows.  Changed GDBTK_FILENAME
	to GDBTK_LIBRARY, which is now a path to search.
	(gdb_path_conv): New function.  Convert Cygwin32 pathname to
	DOS-style pathname.

	* aclocal.m4, configure.in: Changes for Windows builds.

	* configure: Rebuilt.
