The default set up for Debian (stable at least) is to run a 64 bit
kernel and 32 bit userland on Sparc v9 processors.  Unless you have
binaries that are specifically compiled for 64 bit operation then your
programs will be 32 bit.  A program like this:

#include <stdio.h>

int main (int argc, char **argv) {
	printf("%d\n",sizeof(int));
	return 1;
}

Should tell you if you've compiled things correctly for 64 bit.  Be
warned though that for almost all applications you probably don't want
64 bit mode.  A neat summary article is:
