I would say that's too much, for example of the three Unicen I've
access to, digital UNIX 4.0, HP-UX 10.20 and Solaris 2.6, only the last
one provides snprintf().

In Solaris 2.6 and newer yes, earlier version didn't have it (I know
this because I once compiled Mutt, which uses snprintf() (native if
available, compiles own implementation if not), under 2.6 while there 
was still also 2.5 machine, where that binary then failed to run...

Could be, but there's still many older systems around for sure.
