And even better news are that it appears to be possible to squeeze out a
register at the cost of [presumably] slight performance degradation on
Pentium II and earlier. So how does it sound? I mean that we omit cast
assembler implementation in shared context and trade some DES
performance on PII?

^^^^ I wonder if anybody can compile this "extern int foo; int bar()
{return foo;}" one-liner with gcc -fPIC -O -S a.c on *BSD and post the
assembler output?
