Hello,

I want to supply a patch for the released gdb 6.3, that fixes partially  
the gdb bugs

gdb/1091: Constructor breakpoints ignored
gdb/1193: g++ 3.3 creates multiple constructors: gdb 5.3 can't set  
breakpoints

I was really confused, why my programs to not stop at the breakpoint in  
constructor/destructors. Now i know, it is not the fault of my programs ;)  
Since this anoying problem seems to be in gdb since the gcc 3.x release, i  
guess, no one else a) has this problem (i don't believe so) or b) will not  
fix it. So i did it ;)

This modification is only made for commands like "break  
[source]:<lineno>". For C++ constructors and destructors, the patch  
creates more than one breakpoint at the source at lineno, but each  
generated breakpoint will have another address!

NOTE: this is only a simple "hack". I have spent only one day to get into  
gdb source code and do the modification.
It would be better, to create only one breakpoint in such C++ constructors  
and destructors and assign multiple addresses to it. But this needs a huge  
modification of gdb, i guess ;)

ChangeLog:

	* breakpoint.c linespec.c symtab.c symtab.h
	  Add better support for breakpoints in C++ constructors
	  and destructors.

I hope this patch is helpful, maybe some of you can do it into gdb or even  
use it as a base for a better patch fixing 1091 and 1193 ;)
