we have now
/* codes not really needed but cleaner when testing */

#define pdftex_version  40  /* these values will not change any more */
#define pdftex_revision "0" /* these values will not change any more */

and we can change them

#define pdftex_version  140  /* these values will not change any more */
#define pdftex_revision "0" /* these values will not change any more */

but in luatex
a macro package can better do \newcount\pdftexversion \pdftexversion=140
because very likely they will disappear in luatex 1.0 .
