Follow-up Comment #1, bug #37031 (project octave):

I have a test program (below) that looks to do the job.

#include "umfpack.h"
main ()
  double stats [2];
  umfpack_tic (stats);
  umfpack_toc (stats);
  return 0;

If built without the SuiteSparse lib I get;

$ gcc -o conftest conftest.cc -I/opt/local/include -L/opt/local/lib 
Undefined symbols for architecture x86_64:
  "_SuiteSparse_time", referenced from:
      _umfpack_tic in libumfpack.a(umfpack_gn_tictoc.o)
      _umfpack_toc in libumfpack.a(umfpack_gn_tictoc.o)
ld: symbol(s) not found for architecture x86_64

If built with the SuiteSparse library there is no error.

$gcc -o conftest conftest.cc -I/opt/local/include -L/opt/local/lib -lumfpack

Looks like this will be easy to use to create a changeset to allow Octave to
link against SuiteSparse 4.0.x.  I have a busy schedule and may not get to
this quickly.  If anyone is in a hurry, please feel free to take this on.
