In a testdir build on Mac OS X 10.5.8, I see these test failures:
FAIL: test-snprintf-posix
FAIL: test-sprintf-posix
FAIL: test-vasnprintf-posix
FAIL: test-vasnwprintf-posix
FAIL: test-vasprintf-posix
FAIL: test-vsnprintf-posix
FAIL: test-vsprintf-posix
In particular:
$ cat test-vasnprintf-posix.log
../../gltests/test-vasnprintf-posix.c:4245: assertion 'strcmp (result, " 33")
== 0' failed
FAIL test-vasnprintf-posix (exit status: 134)
This test shows a Mac OS X bug: %#.0x with argument 0 produce "0" instead of "".
The bug is fixed in Mac OS X 10.7.0.
It's old, but since this platform is more useful for debugging than
newer macOS releases (as it has a working gdb and a working 'dtruss'),
I'm adding a workaround.

*printf-posix: Work around bug with %#.0x on Mac OS X 10.6.
* lib/vasnprintf.c (VASNPRINTF): Enable NEED_PRINTF_UNBOUNDED_PRECISION-
guarded code also for NEED_PRINTF_FLAG_ALT_PRECISION_ZERO. Set
prec_ourselves to 1 if NEED_PRINTF_FLAG_ALT_PRECISION_ZERO, precision is
0, and the directive is 'x' or 'X'. If prec_ourselves, remove the "0"
output if required.
* m4/printf.m4 (gl_PRINTF_FLAG_ALT_PRECISION_ZERO): New macro.
* m4/vasnprintf.m4 (gl_PREREQ_VASNPRINTF_FLAG_ALT_PRECISION_ZERO): New
macro.

gl_PRINTF_FLAG_ALT_PRECISION_ZERO and test its result.
