# We need includes from this so we take it from the
# precompiled sources.  This saves us having to build the other
# TCL bits prior to this package.
# Infact, UNLESS you're building "tcl" in a chain prior to this package
# then you'll need to unpack the compiled source resulting from the "tcl" build.
# So really it's easier to leave this stuff in at all times.
