This is awesome.  I finally have a recent tip build.  I do have one more 
question.  I have a bunch of libraries I am linking against (lots of GTK-Quartz 
stuff for a native OctaveDE on OSX) and have the issue of linking the 32bit 
Octave build with the 64 bits everything else.  Rather than have to recompile 
everything else, is there some way to get the 64 bit Octave working on OSX?  I 
tried changing the -m32 to -m64, but then some configure tests for BLAS fail.  
If I exclude -ff2c I get a Trap Error on one test and the other succeeds, while 
if I use f2c the first test succeeds and the second fails.  I think it has 
something to do with BLAS and the expected integer size (4 vs 8 bytes).
