I will investigate this but it seems to be a DJGPP 2.04 issue.  I will answer
ASAP.

I have also tried djdev203 and it was possible to compile it out-of-the box
and seems to work.  Neither less the emacs code expects that the library
provides snprintf, but this is not the case for djdev203.  This is also the
case for many other GNU ports I have done lately where I had to add
to the sources the snprintf code taken from the repository so they can
be compiled with DJGPP 2.03.
I got this error message:
