[Qt-creator] ubuntu 9.10 amd64, debugging helpers do not build

[Grego]

Hi,

I had to add

#include <stdint.h>

to gdbmacros.cpp for the debugging helpers to build.  Otherwise it
would complain:
gdbmacros.cpp:636: error: expected type-specifier before ‘uintptr_t’

After that it worked sometimes, gdb would crash most of the time, but
not always.  Browsing this list I see I should downgrade the gdb to
6.8... seems like I need to build it myself, as it doesn't seem to be
in ubuntu repository.

Cheers,

Grego
