Summary:                    using -xopenmp precludes gcc usage
Description: 
when using imagemagick's API and pkgconfig we inherit the -xopenmp flag
which is not supported by gcc.

I wonder if the usage of this option is reasonable for this project.

My recommendation is to remove this option.

Well, imagemagick's configure script explicitly checks for and adds xopenmp
by itself so what implications it might have, trying to remove it manually,
is unknown

To remove it manually, if you use Sun Studio C compiler has the effect of
not using parallelism which I don't think is an issue.

In my opinion, you have 2 solutions:

1. provide a non parallel version compiled with Sun Studio, possibly in
addition to a parallel one

2. build with gcc
