Hi,

	I use gdb at work for some time now. We currently develop a
multiplatform software which heavily use STL templates. As a result,
it's always difficult to me to debug such code.

	I tried to find a way to debug more efficiently by using gdb scripts
that were able to dump std::vector or std::list, but it was always
painful.

	So, yesterday, I decided myself to look at the code of GDB. After a
quick look, I wrote this patch. I know that it's not very clean, and
that it makes many assumptions about STL containers, and that it cannot
be considered as a long term feature for GDB, but, believe me, it's very
very usefull !

	Now, I can look at the content of list, vector, set, map, multiset,
multimap and string simply with the classic "print" command of GDB.

	Two switchs and a parameter are introduced :

 * set print stl on / set print stl off
default is off. Controls the type of dumping (classic or "easy")

 * set print stl_array_compatible on / set print stl_array_compatible
off
default is on. Controls the kind of formating of STL container when stl
print is on.

 * set print stllimit N
 set the maximum number of items we could dump when printing an STL
container to N. 0 means unlimited

	I hope it could be useful for someone.

Sincerely
Vincent Benony
