The Fortran dynamic arrays debug info fix got committed for 4.3 by Jakub Jelink:

While it is correct it is in fact more a general problem of all of the upstream
Fortran testcases as AFAIK `g77' binary/link is just no longer present in GCC.
Using now a workaround in:
	http://cvs.fedora.redhat.com/viewcvs/*checkout*/rpms/gdb/devel/gdb.spec
	cd $the_build_tree_root
	# g77 executable is no longer present in Fedora gcc-4.x+.
	g77="`which gfortran 2>/dev/null || true`"
	test -z "$g77" || ln -s "$g77" ./g77

Also the whole Fortran dynamic arrays patchset no longer applies well so it was
forward-ported for 6.8pre in between.  But only in its merged form:
	http://cvs.fedora.redhat.com/viewcvs/*checkout*/rpms/gdb/devel/gdb-6.8-bz377541-fortran-dynamic-arrays.patch
