That's a little harsh. :-) The return value of vsnprintf was changed in
C99 (compared to C89). It's something that really needs to be checked in
configure.in (basically it could return the current glibc number, the
current Microsoft number or -1, like older glibc's did -- although I'm
not sure what standard the latter behaviour was following).

The vsnprintf and snprintf functions are really ugly to work with
portably, since you really want to be able to assume a C99-compatible
compiler, but that is often unrealistic.
