we should believe the type of a PCC 'short' argument,
but shouldn't believe the address (the address is
the address of the corresponding int). Note that
this is only different from the BELIEVE_PCC_PROMOTION
case on big-endian machines.
My guess is that this correction, as opposed to changing
the parameter to an 'int' (as done below, for PCC
on most machines), is the right thing to do
on all machines, but I don't want to risk breaking
something that already works. On most PCC machines,
the sparc problem doesn't come up because the calling
function has to zero the top bytes (not knowing whether
the called function wants an int or a short), so there
is no practical difference between an int and a short
(except perhaps what happens when the GDB user types
"print short_arg = 0x10000;").
Hacked for SunOS 4.1 by gnu@cygnus.com. In 4.1, the compiler
actually produces the correct address (we don't need to fix it
up). I made this code adapt so that it will offset the symbol
if it was pointing at an int-aligned location and not
otherwise. This way you can use the same gdb for 4.0.x and
4.1 systems.
If the parameter is shorter than an int, and is integral
(e.g. char, short, or unsigned equivalent), and is claimed to
be passed on an integer boundary, don't believe it! Offset the
parameter's address to the tail-end of that integer. */

Thus code like this:

is wrong because if *pp starts out pointing at '\0' (typically as the
result of an earlier error), it will be incremented to point to the
