Not really, because glob() wouldn't enforce any preference over which
of multiple versions to pick. If anything, it would do exactly the
wrong thing, preferring an older tclsh version over a newer one.

But I agree with Andres' complaint that just duplicating the code isn't
the best way. The configure script has a loop that's basically like

for f in tclsh tcl tclsh8.6 tclsh86 tclsh8.5 tclsh85 tclsh8.4 tclsh84 tclsh8.3 tclsh83
do
... break if $f is the right one
done

Seems to me that a similar coding pattern in the MSVC script is a
reasonable way to go.
