sign-extends the PC.  Here is a piece of his original message explaining

Anyway, the fix is simple and Andrew himself provided it for us.  It
took a while for me to figure out how to trigger the bug (in order to
write a testcase for it), but I finally made it.
The attached patch fixes the problem (by casting to `unsigned long'
instead of just `long'), and also includes a testcase to reproduce the
issue.

This fixes the remaining issues necessary to make the DWARF reader
-Wpointer-sign clean.  The 'filename' bit should be obvious.
'constant_pool' holds the contents of an obstack, which are 'char *'.
gdb_byte would work too, but it'd need more casts elsewhere, so I just
chose the minimal approach.  Any way would be fine with me.

The mips packet payload is ASCII, so it makes sense for
mips_send_packet and mips_receive_packet to expose 'char *'-based
interfaces, as currently they do.  But, mips packets have a binary
header, so if you look at e.g., mips_receive_packet's implementation,
you'll see "unsigned char" buffers in use.  I find it the most natural
to make the payload pointer passed to mips_cksum 'char *' too.
The other changes are straightforward adjustments -- a checksum is
naturally unsigned, and there's one point where we're reading a bfd section.
