Further testing on that box shows that its ancient gcc (2.95.3) doesn't
know "z" either, which means that the patch produces a boatload of
compile warnings like this:
mcxt.c: In function `MemoryContextAllocZero':
mcxt.c:605: warning: unknown conversion type character `z' in format
mcxt.c:605: warning: too many arguments for format
While I am not really expecting this gcc to compile PG cleanly anymore,
the idea that we might get many dozen such warnings on more-current
compilers is scarier, as that might well interfere with people's
ability to do development on, say, Windows. Could somebody check
whether MSVC for instance complains about format strings using "z"?
Or shall I just commit this and we'll see what the buildfarm says?
