| Building tip (9136) using GCC 4.3.3 on Solaris fails in liboctave/Quad.cc:
| 
| Quad.cc: In function 'octave_idx_type float_user_function(float*,
| int&, float*)':
| Quad.cc:110: error: 'access_float' was not declared in this scope
| Quad.cc:120: error: 'assign_float' was not declared in this scope
| 
| The attached patch removes calls to the nonexistent utility functions
| access_float() and assign_float() which are made when "sun" and
| "__GNUC__" are defined.

| Applying the patch makes tip build successfully for me.  The build

| 
| octave:2> quad ( @(x) x, 0, 2 )
| ans =  2

I checked in the change, but what about

  quad (@(x) x, single (0), single (2))

?  Are you using the Sun Fortran compiler?  My guess is that it will
work, and that GCC and the Sun Fortran compiler will handle floats in
a compatible way, unlike for doubles.

Thanks,
