Have they now?  Tell me again how many years Turbo C has been around.  Tell
me again how how many years the dpANS and pANS have been available for
compiler vendors.  What's your definition of "several years?"

The answer to your first question is obvious.  They don't have the benefit
of your wisdon and knowledge at their disposal.  Had they these things, they
would have had a satisfactory compiler out for "several years" now.

The answer to your second question requires more information.  Please define
"Standard UNIX C" for us and maybe we can help.  Some compilers supported
the "=op" expressions as well as the current "op=" type.  Some compilers
were silent about it (Whitesmiths, for example), and some would issue a
warning, and in the case of your example, decrement p.

Go stand in the corner with those who still think 'x' is an int.

Sheesh!
