You compiled it on a -current (gcc-3.2.1) system? It does will not
compile on mine, current as of 6 Feb. I noticed the problem
with -current from 2 Feb, so I can't comment on anything before
that date.

#include <iostream.h>

return 1;
}
void xxx (ostream& os) {
os << ' ';
os << "out\n";

agreed :-)
| I'd suggest feeding back patches to the jdk maintainer.
the jdk code uses the <iostream.h> header, and will not compile on
my system w/o some tweaks.
cheers.
