I get the same error with SuSE-8.2 and lilypond 1.8.1. 

If I'm right, the problem is that the configure script concludes that
snprintf is not provided by stdio.h although it is. If I change in
config.h the setting for HAVE_SNPRINTF and HAVE_VSNPRINTF, the file
compiles. (I get another error in the directory lily, but I assume that this
is not related to this problem.)

Since I always avoided function pointers, I cannot judge whether the test in
configure should work. Here is the exerpt from config.h:
