Yes, I accepted the 'BUILD_FLAVOR=ActivePerl' option which sets USE_MULTI
and USE_ITHREADS.
'Perl - V' declares that 'useithreads=define' and 'usemultiplicity=define'.
It also mentions '-DPERL_IMPLICIT_SYS' as one of the ccflags, so I assume it
has also been set.

No warning about that .... but then I've used the -O1 switch because that's
the one specified in the makefile.

Should I try changing that to -O2 ?

There's a comment in the makefile that says "-O1 yields smaller code, which
turns out to be faster than -O2".

I've since tried benchmark comparisons of some other code and while mingw
perl is generally faster, the difference in performance is generally far
less pronounced than for the code I posted.

Cheers,
Rob
