------------------------------------------+---------------------------------
 When I try to compile GNU Emacs 24.0.92 with GCC 4.0 on Mac OS X 10.6.8
 the configure script stops prematurely with:

 {{{
 checking for libXaw... configure: error: Lucid toolkit requires X11/Xaw
 include files
 }}}

 which config.log explains:

 {{{
 cc1: error: unrecognized command line option "-fopenmp"
 }}}

 This too modern switch is introduce from any of these PC files:

 {{{
 /opt/local/lib/pkgconfig/ImageMagick.pc:Cflags: -I${includedir} -fopenmp
 /opt/local/lib/pkgconfig/MagickCore.pc:Cflags: -I${includedir} -fopenmp
 /opt/local/lib/pkgconfig/MagickWand.pc:Cflags: -I${includedir} -fopenmp
 /opt/local/lib/pkgconfig/Wand.pc:Cflags: -I${includedir} -fopenmp
 }}}

 One of them is asked by configure:

 {{{
 config.log:configure:10891: result: -fopenmp
 -I/opt/local/include/ImageMagick
 }}}

 and than this compiler option is used. This is similar to tickets
 [https://trac.macports.org/ticket/15945] and
 [https://trac.macports.org/ticket/24944].

 What about setting up a directory of backward compatible PC files without
 this -fopenmp switch?


 My work-around is to copy a modified version of
 /opt/local/lib/pkgconfig/ImageMagick.pc into the root directory and modify
 PKG_CONFIG_PATH to contain ``.´´.
