Everything compiles with gcc just now.  There is like one
link error in hyper.exe because the tclstubs library is
missing from the link line.

The runtime problems seem to do with a Tcl_Preserve call
setting the interp pointer to NULL, but I've not tracked
down why.  I think I've seen similar problems with the
gcc compiled wish83, however some thing about Insight's Init
code let's it avoid this problem.
