The problem that the tile06.kit's pkgIndex.tcl script
is trying to avoid is: the theme engine calls a Tk private
routine that wasn't added to the private stubs table
until Tk 8.4.6.

So if you compile Tile against post-8.4.6 private headers,
and load it into a pre-8.4.6 interp, it will crash.

Other possibilities are:

(1) Compile with -DNO_PRIVATE_HEADERS (see tkTheme.c).
Then tile.dll will declare and call the offending function
directly instead of going through the stubs table.
This may cause a runtime linker error, depending on
the platform and how the core was built.

(2) Compile against pre-8.4.6 headers.  This will have basically
the same effect as (1), plus you'll get a compiler warning.

(3) Build tile --enable-static and link libtile.a / TILE.LIB
into the Big Wish / starkit runtime / whatever.  Tile_Init()
supports the usual tcl_findLibrary conventions for locating
its init script.

If it doesn't die with a runtime linker error, and doesn't
crash when you create and map a widget, you should be OK.
