vasprintf is a GNU extension.  glibc implemented vasprintf approx. on:
	96aa2d94a2355cdc55c96e808d14a0e7f2ebe77d Date: Mon Nov 20 03:48:11 1995 +0000
while %z glibc implemented approx. on:
	e852e889444a8bf27f3e5075d064e9922b38e7e2 Date: Tue Jul 28 16:26:04 1998 +0000

I do not say there cannot exist an OS with vasprintf not supporting %z but it
seems improbable enough to me to handle it specially before such OS is found.

As mentioned in the original mail it can be still easily fixed up after
a first user of such OS bugreports it.


Thanks,
Jan
