[Nauty-list] 32 or 64 bit

How does the makefile for nauty determine whether to create a 32-bit  
or 64-bit version?

I ask because I have just compiled on a Solaris machine

$uname -a
SunOS russell.newton.cam.ac.uk 5.10 Generic_127111-05 sun4u sparc  
SUNW,Sun-Fire-V490 Solaris)

This is a 64-bit machine that is apparently running in 64-bit mode

$ isainfo -v
64-bit sparcv9 applications
         vis2 vis popc
32-bit sparc applications
         vis2 vis popc v8plus div32 mul32

but when I just do ./configure; make all; I end up with a 32-bit  
version of nauty...


Can I force it to give me a 64-bit version?

(When I do the same on my 64-bit Red Hat machine, it gives me 64-bit  
version of nauty)
