Thank you for your patch. I believe that all the problems addressed in 
your patch have been corrected in more recent gdb releases. It is always 
best to double-check CVS HEAD.

I realize it has been quite a long time since an official Insight 
release was made, and I apologize for that. I still hope to have an 
official 7.4 release, but I have encountered some difficulties which are 
delaying the release.

Thank you again for your help,
Keith
