Stop.

In working on a patch to allow strictness for how Tcl exports symbols that are
only in the Stubs table (tip#60), I just discovered a problem. generic/tclTest.c
is calling functions that ARE NOT EXPORTED. Because tclTest.obj is linked into
the shell (tclAppInit.c; tcltest.exe), there is no visibility to those 9
functions because they live hidden (unexported) in tcl85.dll. It only works
today because of the side-effect of the EXTERN macro exporting functions from
the library which has never been correct.

The proper fix, I think, is to export them through the internal Stubs table.
Anyone have an opinion on this?

FYI: TIP#60 reduces the exports to 695 from 970. The above 9 function are part
of the 275 that are not "blessed" to be exported.
