buffered output on solaris?

When including shared object libraries into root, I've come across the
following peculiarity: the output seems to be buffered on a solaris4
platform. When I have a class with the following member:

Foo::Bar() {
cout << "Print something\n";
}

and execute it, nothing gets printed out. It takes a number of iterations
of the function before anything gets printed out. However, if I do

Foo::Bar() {
printf("Print something\n");
}

this prints out immediately.

I don't have this problem on a Linux system.

- is this a feature or a bug?

- if this is intentional, is there something that I can set to force the
output buffers to be flushed on every 'cout' statement?

The platform is:
uname -a: SunOS starsu00 5.6 Generic_105181-13 sun4u sparc

and root is: ver 2.21/08

thanks... Charles.
