* elfread.c (elf_symtab_read): The calculation of 'offset'
         must be done for each symbol, not just once. The index

        * value.h: Add prototype for _initialize_value.

        * defs.h: Include sys/types.h or stddef.h to get size_t.

        a prototype for this function.

        Cast parameters passed to make_cleanup to use the new
        make_cleanup_func typedef.


More warning cleanups.  There are still a bunch of places where the first
argument to make_cleanup is not cast to (make_cleanup_func); these are
either due to the function fitting the make_cleanup_func specification
already (e.g. free()) or they are in files that weren't compiled when
I did my make on a Linux native system.  Bwahahaha.  You can see them
like this:

grep make_cleanup\  * | grep -v make_cleanup_func

I'll surely go back and clean up the remaining suspicious calls in
GDB one of these days. :-)

Andrew Cagney 4dbdbfc4d3 o Fix code deleting psymtab entry from objfile's list.
Only worked if the first element in the list was
	being deleted.
o	When MAINLINE (reading main objectfile and need to
	clear out old data), change elfread.c so that the
	psymbol table is emptied once (in elf_symfile_read)
	instead of multiple times in each *_read_psymtab
	function.
o	For elf_symfile_read, load dwarf2 symbols last
	(so that they are searched for first).
o	In mdebug_psymtab_read, delete check to see if
	symbols for current source file already loaded.
	Test doesn't work for .h files.  Above change
	works better
