------- Comment #3 from baryluk at mpi.int.pl  2007-06-21 11:31 -------
Timings (n=1000, Athlon 1GHz) of code from comment #0 (zero changes)

dmd-1.015: 1.95 sec
dmd-1.015 -version=foo: 2.03 sec

dmd-1.015 -O -inline: 1.03 sec
dmd-1.015 -O -inline -version=foo: 1.60 sec

using bash builtin function time. optimised version without foo is better
becouse local variables can be properly alligned on the stack and access to
them can be optimised.
