Hi!

My patch seems to be incomplete. The way it is, including blt.h withou prior tcl.h leads to compile errors because Tcl_AppInitProc is undefined. This will break configure scripts which try to find blt.h by compiling simple files with #include <blt.h> in them. Here is one possible fix - included tcl.h inside blt.h.</blt.h>
