Yes, at least some of us were quite aware of this.  There are also other
nonstandard vendor extensions to fprintf() format specs in existence.
I've argued numerous times with C implementors that using %p for "Pascal"
(counted) strings encouraged non-portable programming.  Unfortunately
Apple's ToolBox interfaces are designed for Pascal, not C; the same malady
later showed up on the Apple IIGS.  There are better solutions, though,
such as providing Pascal-to-C string translator functions in the C library.
Note that ByteWorks' ORCA/C for the Apple IIGS will remain non-compliant
with the C Standard unless Mike Westerfield reverses his decision about
this.  (ORCA/C does provide conversion functions, so %p=>Pascal is not
really necessary.)

I have no idea whether or not the Mac compilers will ever become Standard
conforming.  From what I hear, most of them come nowhere close to
providing a full hosted implementation.
