When the scanner is run during the build it cannot find some of the glib2 header files, one example of which is include/glib/glib-2.0/glib/gmacros.h.  All the normal compiling and linking seems to work fine, so the problem is apparently limited to the scanner.  The following patch (and a similar one for tests/offsets/Makefile.in) fixes the problem.

To add some more details, here is a bit more information.

First, I should have said that the problem is with g-ir-scanner (part of devel/gobject-introspection) creating *.gir files.

Second, here is an example of a failing command during the build of devel/atk:

Caught exception: <class 'distutils.errors.CompileError'> CompileError(DistutilsExecError("command 'cc' failed with exit status 1",),)

Adding the value of ${INTROSPECTION_CFLAGS}, which includes paths to the glib-2.0 directory with the missing file, to the definition of CFLAGS (which shows up in the command line) does not help.

Is it possible that the buildlink machinery is messing with this command line?

Any ideas?

Thanks for your help.

Cheers,
Brook
