`works for me'.  I tested it with:
gcc version 2.95.3 20010315 (release) (NetBSD nb3)
gcc version 2.96 20000731 (Red Hat Linux 7.2 2.96-112.7.2)

Looking at the first problem:

breakpoint.c: In function `insert_breakpoints':
breakpoint.c:916: warning: format not a string literal, argument types 
not checked

it revealed this little `gem':

   static char message1[] = "Error inserting catchpoint %d:\n";
   static char message[sizeof (message1) + 30];
	...
         sprintf (message, message1, b->number);

While getting the option working with a current GCC could mean more 
work, I'm not convinced that it's a bad idea.
