Details:

Building octave 3.8.3 using gcc with the gui enabled on a homebrew mac,
there's an error emitted that terminates the build of the gui:

 _GL_WARN_ON_USE (gets, "gets is a security hole - use fgets instead");


The problem is fixed simply by commenting out that line of libgnu/stdio.h

While I'm at it, here's a configure line that successfully builds octave using
the homebrew install of gcc 4.9:

./configure CC=/usr/local/bin/gcc-4.9 CXX=/usr/local/bin/g++-4.9
CFLAGS="-I/usr/local/include -Ofast -m64 -march=native -mtune=native"
CPPFLAGS="-I/usr/local/include" F77=/usr/local/bin/gfortran-4.9
FFLAGS="-I/usr/local/include -Ofast -m64 -march=native -mtune=native"
LDFLAGS="-L/usr/local/lib/gcc/x86_64-apple-darwin13.3.0/4.9.1
-L/usr/local/lib" FLIBS="-lgfortran -lquadmath -lm" --with-framework-carbon
--without-x LLVM_CONFIG=/usr/local/bin/llvm-config-3.5
