*printf() is not part of the compiler, but the C library (libc); GNU 
glibc (used on Linux) provides it, while Solaris doesn't.  There's been 
some discussion about it, but there are several incompatible asprintf() 
interfaces around and it's not clear which one should be implemented.

Someone else already provided a version using snprintf, but you could 
also use g_vasprintf() from glib, or the version from gettext's 
libintl.h (which means you need to include <libintl.h> and link against 
- -lasprintf, both of which live in /opt/ts/gettext).  I personally find 
the snprintf solution the best and this is what I use in my own code.
