If you are using --enable-64, then I think you should be using the 
cholmod_l_X functions anyway.  I recently fixed some problems with the 
configure script related to these checks:

http://hg.savannah.gnu.org/hgweb/octave/rev/eb572251b7c6

Also, whenever someone asks about --enable-64, I have to ask whether it 
is really needed.  Have you read

http://www.gnu.org/software/octave/doc/interpreter/Compiling-Octave-with-64_002dbit-Indexing.html#Compiling-Octave-with-64_002dbit-Indexing

?  Note that --enable-64 is not required for Octave to use more than 2GB 
of memory, but to allow indexing of more than 2^31 elements in a single 
array.  Do you really need to use arrays that large?
