/****
* The perl API docs state that PERL_SYS_INIT3 should be called before
* allocating interprters. Unfortunately, on some platforms this fails
* in the Perl_do_taint() routine, which is called when the platform is
* using the system's malloc() instead of perl's own. Other platforms,
* notably Windows, fail if PERL_SYS_INIT3 is not called. So we call it
* if it's available, unless perl is using the system malloc(), which is
* true when MYMALLOC is set.
