The GraphicsMagick log file includes ...

checking whether the gcc -std=gnu99 linker 
(/usr/llvm-gcc-4.2/libexec/gcc/i686-apple-darwin11/4.2.1/ld) supports shared 
libraries... no
checking dynamic linker characteristics... no

The Octave log files includes ....

checking whether the gcc linker 
(/usr/llvm-gcc-4.2/libexec/gcc/i686-apple-darwin11/4.2.1/ld) supports shared 
libraries... yes
checking dynamic linker characteristics... darwin11.4.2 dyld

Is there a bug there or does the std matter when linking?
