Yes. I thought it was automatic, tho.
What to do?

Curtiss-Wright Controls, back when they were called Synergy.

The military ends up supporting ancient systems for a long time.
I don't think I have the option of upgrading the OS on these beasts,
especially when it involves a new binary format.
That would be nice, tho, especially if it made it possible to run subversion.

"grep -r sinl /usr/include" finds nothing.
math.h defines sin and sinf with various underscores attached, 
using token pasting, but no mention of sinl.
Similarly for fabs and cos which I checked.

The CWC VSS4 contains four powerpc G4's, the 7400.
