The one at http://www.delorie.com/djgpp/doc/libc/
It doesn't seem to say which version it refers to,
but it's obviously not in sync with the DJGPP
release I have (2.03 with minor upgrades).

I don't think so, and the compiler itself appears to agree
with my interpretation:
    gcc -c -O2 -I. -o nasm.o nasm.c
    nasm.c: In function 'main':
    nasm.c:189: warning: incompatible implicit declaration of
    built-in function 'snprintf'

However, the link error suggests it's not built-in after all.
Perhaps someone removed it and forgot to update the manual
and error messages.
