This coding will fail on a C90 compiler that's on a platform that supplies
snprintf, which is a combination I don't find real surprising --- probably
"gcc -ansi" would behave that way on many machines.

Apparently the expectation is that people using such platforms will
manually fix things by defining HAVE_SNPRINTF=1.  I'm not sure it's
possible to do better without autoconf.
