Hi,
I noticed gdb/dwarf2-frame.c:1922 (and :1950) calls dwarf2_get_section_info 
with unsigned long* (5th argument). The function expects a bfd_size_type * 
(a pointer to an unsigned long long on my machine). Thus the compiler issues 
a warning and the gdb build fails because of -Werror. Is it sufficient to 
just cast to (bfd_size_type *) or am I missing something?
