I've just created some new config files for my automated build process
that drop the specification of the local library for snprintf(), and
did builds of m4-1.4.7 with both cc and with gcc; all tests were
successful, and I've installed the cc build.

It is nice that m4 is able to adapt to a missing snprintf() (my own
packages do this too, by falling back to the unsafe sprintf()).
