this explanation sort of confuses me.  The current situation really
*is* what Andrew Haley proposed.

I guess that though the comps file does not have arch-specific bits,
the installation is determined by arch-specific dependencies in the
packages.

That was exactly what has brought my attention to this:
the differences between the two java's (e.g. that jni.h is installed
to the default include path by gcj but not by openjdk, different
javadocs) make the good old generic
	BuildRequires: java-devel
very problematic, so I had to change it to
	BuildRequires: java-1.5.0-gcj-devel

Well, my package builds fine with gcj and my conscience is clear as I
have reported this, so all is fine.  :-)
