[rfa/doco] PROBLEMS: add gdb/1516

[mec.gnu@mindspring.com (Michael Elizabeth Chastain)]

This patch adds a description of gdb/1516 to the PROBLEMS file.
This is a regression with g++ 2.95.3 -gdwarf-2 and we've decided
not to fix it, so I want to document it.

By the way, this file needs (1) a copyright notice and (2) to be
updated from "gdb 6.0" to "gdb 6.1".

Leaving those issues aside -- okay to commit this?

+ gdb/1516: [regression] local classes, gcc 2.95.3, dwarf-2
+ 
+ With gcc 2.95.3 and the dwarf-2 debugging format, classes which are
+ defined locally to a function include the demangled name of the function
+ as part of their name.  For example, if a function "foobar" contains a
+ local class definition "Local", gdb will say that the name of the class
+ type is "foobar__Fi.0:Local".
+ 
+ This applies only to classes where the class type is defined inside a
+ function, not to variables defined with types that are defined somewhere
+ outside any function (which most types are).
