mkoctfile does not understand "-fopenmp" from ImageMagick

[Alex Lancaster]

Hi there,

I'm one of the maintainers of the octave/octave-forge packages on
Fedora and it appears that there are some problems with mkoctfile not
accepting certain flags from ImageMagick's "Magick++-config",
specifically it doesn't (yet) understand the -fopenmp GCC flag:

Magick++-config --cppflags` `Magick++-config --ldflags` 
mkoctfile: unrecognized argument -fopenmp 

This occurs with octave 3.0.3, compiling one of the octave-forge
subpackages and currently means that the Fedora octave-forge package
on rawhide fails to build.  The ImageMagick maintainer says:

 "Either way, as ImageMagick gets compiled with -fopenmp, adding
 -fopenmp to its LDFLAGS is correct. So I'm closing this as not a
 bug. for octave-forge I advice you to replace -fopenmp in the flags
 with -lgomp."

(from http://bugzilla.redhat.com/show_bug.cgi?id=477577#c2 )

For more information and background see the Fedora bug here:

Please advise how best to proceed and if octave can be modified to
allow the build to proceed (we can carry a local patch until such time
as the fix is applied upstream).

Thanks,
Alex
