MinGW setjmp SEGV

[Andrew STUBBS <andrew dot stubbs at st dot com>]

Hi,

I have been trying to build Insight 6.1 (patched into GDB 6.3) for MinGW  
(and Linux and Solaris but they weren't much trouble).

The problem I hit has been previously reported here:  
http://sources.redhat.com/ml/insight/2004-q1/msg00021.html.

There are a number of patches required to make it build, but most are  
trivial and may not be relevant since 6.1 so I shall not post them.  
Basically I had to check whether the cygwin filename-handling tcl  
functions exist before using them, define __INSIDE_CYGWIN__ in a couple of  
tcl/tk files, and rename the hooks because they now have a 'deprecated'  
prefix.

However, the most serious failure was caused by broken code in the tcl dll  
screwing up the SEH and causing setjmp to fail. This problem has been  
fixed in the latest tcl at tcl.sourceforge.net.

The attached patch (code copied from sourceforge) is sufficient to fix the  
issue. Note that I have included the diff of the whole file and it  
includes one of the minor changes mentioned above.

Hopefully this patch will help others who have hit the same problem.
