As you wrote later, since pure storage comes out of a static array, it
is hard to believe the OS or the compiler can make the difference.
But for the record, the compiler I used was gcc 3.4.5.

I don't know whether average is the right measure here (we won't know
for sure until we discover the reason(s) for the discrepancy), but
how's this: loading subr.elc took 14KB more in Rainer's build than in
mine, bindings.elc took 23KB more, utf-16.elc took 15KB more, etc.  I
think these are very large differences.

AFAIU the byte compiling, there should be no variation at all on the
same architecture and OS, as long as the same files are loaded.
