------------------------------------+---------------------------------------
 Without the FFLAG '-ff2c' with gcc43 and gcc44 a check for whether certain
 BLAS routines are called correctly during configure will fail and as a
 result the build will use the reference BLAS rather than the optimized
 BLAS available in the Accelerate framework. Adding,

   configure.fflags='-ff2c'

 corrects this problem and allows Octave to compile against the optimized
 library.
