Due a bug in Solaris I was tracking in 2.5 and 2.5.1, it turns
out there is an snprintf in solaris' libc, and I will do what
I can to post a patch so we don't have to use an outside
source.

This is a snippet of code an engineer at Sun sent me when they
were confused about some code which couldn't find snprintf under
2.5/2.5.1.

It looks like all we have to do for 2.5/2.5.1 support is define
#define snprintf __snprintf
#define vsnprintf __vsnprintf

I will check my 2.5.1 system tommorow and see what I can do
about patching. (Anyone got a snippet of Autoconf to
test various versions of a particular Operating system)

Let me know if this fixes the 2.5/2.5.1 problem

Thanks

Ben
