Re: expect and tclsh give different output from "clock scan"

[Brad Gutt <bgutt3 at yahoo dot com>]

Thanks Keith.  Wow! The Expect binary and the Tcl
binary that I'm using on my PC are both coming from
the same version of Cygwin, and therefore the response
of ::tcl_platform(platform) being different is even a
more serious flaw than the issue with "clock scan"!  I
expect (pardon the pun) that Expect should be using
the exact same source code as Tcl, in fact, I would
have expected Expect to just use Tcl as a
library/framework and just add Expect-specific Tcl C
commands and procs to supply additional functionality,
just like normal Tcl based applications.  Is it that
Expect has an old copy of Tcl source in its tree? If
so, do you or anyone know why that is? Or, better yet,
is there some Expect-specific mailing list in which I
can investigate this problem further, so as to not
bother the insight group with this?

Thanks!
Brett
