If you want to do this, fine...  But you want BOTH "run gdb from the 
build directory" and "debug a version of gdb from the build directory", 
since

gdb run-insight.sh

is probably not going to do what you want...

I actually think that the changes I made to get this all to work are 
good, and SHOULD make it back to the SourceForge Tcl.  The basic 
observation is that as long as you don't move the sources around,  the 
tclConfig.sh files KNOW where all the sources are.  So you should look 
for them (they are VERY likely to be local and easy to find when running 
from the build tree), and not do some dopey groping around a couple 
directories up type heuristics to find the sources - which are not 
guaranteed to be anywhere near the build tree.

I tried to argue this with Brent a couple of years back, but I don't 
think anyone at Scriptics at the time much cared about this, and they 
ALWAYS build in the source tree, so this was not much of an issue for 
them.

But, OTOH, I don't work on this stuff any more, so I am not going to 
commit hari kari no matter what you do...

Thanks for the comments Jim.  You know more of the history of these
things.

Ian,

Now that Tcl is in sourceforge they may be more willing to consider our
changes.  Don't you want to try submitting some of those?  

Of course, this would only help us for 8.4, I guess.  We would have to
use some other solution anyway if we want to use the instaled 8.3 Tcl.
:-(

Fernando
