I guess that they are under a BSD-style licence? I don't think they could
be incorporated into DJGPP for this reason.

Thanks, they have the same prototypes as Alain's implementation.
Unfortunately, they completely ignore the buffer length, which means they
are just hacks! They will not prevent buffer overruns, which is the main
point of {v,}snprintf(). They are band-aids to allow code using snprintf()
to compile when the host system does not have it.
