RE: cygwin runtime woes (was Re: [RFA] ARI fixes for gdbtk directories)

["Pierre Muller" <muller@ics.u-strasbg.fr>]

I debugged the problem a bit:

gdb_loc is call a few times
for 'main' 'MAIN___' 'MAIN__' 'cyg_user_start' 'cyg_start' 
and then finally with '*' which causes the abort.

the first calls all fail with
"No symbol table loaded. Use "file" command"
even though I used ./gdb.exe as arg for run command.

It cycles through that list twice but 
goes behind to finally call
gdb_force_quit a little bit later.

Last call to wrapped_call before this is
gdb_restore_fputs...

bjut this all doesn't help me much,
maybe it explains something for you...
