Did you mean "run -nx ./gdb.exe"?

Odd... Are you sure you erased all of the gdbtk.ini files lying around? 
If "-nx" works, then insight must be finding one of these files somewhere.

Yeah, for whatever reason, iwidgets::scrolledtext seems to be missing on 
your system. I can't even imagine how. Are any of TCL_LIBRARY, 
TK_LIBRARY, ITCL_LIBRARY, ITK_LIBRARY, or IWIDGETS_LIBRARY defined in 
your environment?

From what I can tell, the tcl/tk distributed with cygwin are not usable 
for an insight build: they are missing some internal headers that are 
required to build insight (specifically, tclInt.h and tkInt.h -- 
probably a few more). You *must* use the in-tree tcl, tk, and itcl.

I've verified this on a build of CVS HEAD on my own (ancient) x86 cygwin 
box. If you attempt to use the system-supplied tcl and tk, you will get 
errors about "private headers" missing.

PS. Getting a lot of build warnings that stop the build? Use 
--disable-werror at configure time. I did NOT have to do this on my 
machine...
