you need also
libGLU-devel                             8.0.4-1

install gcc4, gcc-3 is not worth for Octave.

gcc4-core                                4.5.3-3
gcc4-fortran                             4.5.3-3
gcc4-g++                                 4.5.3-3


I assume you are trying to build the development branch as
 octave-3.6.2 is already available on cygwin.

so you will need also
libqscintilla2-devel                     2.6.1-1
libQtCore4-devel                         4.7.4-4
libQtGui4-devel                          4.7.4-4
libQtNetwork4-devel                      4.7.4-4
libGL-devel                              8.0.4-1
libllvm-devel                            3.1-1

and of course
liblapack-devel                          3.4.1-1
libarpack-devel                          3.1.2-1
libqrupdate-devel                        1.1.2-1
libfftw3-devel                           3.3.2-1
libglpk-devel                            4.47-1
libGraphicsMagick-devel                  1.3.16-1
libhdf5-devel                            1.8.9-1
libSuiteSparse-devel                     3.7.1-1
libfltk-devel                            1.1.10-1

I could have still missed something...
