glpk problems on cygwin

[Tatsuro MATSUOKA]

Hello

Because Macro's octave is the official version, so you can set up it using setup.exe.
In category Math, you can find the octave 3.0.1.

However, it seems that all dependencies may not be selected correctly  by cheking only octave 3.0.1.
You have to check the glpk, fftw, suitesparse, qhull, and lapack librariws in category library.
