  Michael, I think there is a cleaner way to accomplish the same thing,
with the nodist prefix. Example (from gnumexp):

# Numexp::Kernel and Numexp::Client interfaces
noinst_LIBRARIES=libnumexp_corba.a libgnumexp_shell.a
nodist_libnumexp_corba_a_SOURCES =		\
	Numexp_Kernel-common.c			\
	Numexp_Kernel-skels.c			\
	Numexp_Kernel-stubs.c			\
	Numexp_Kernel.h
nodist_libgnumexp_shell_a_SOURCES =		\
	GNumexp_Shell-common.c			\
	GNumexp_Shell-skels.c			\
	GNumexp_Shell-stubs.c			\
	GNumexp_Shell.h

CLEANFILES = $(nodist_libnumexp_corba_a_SOURCES) $(nodist_libgnumexp_shell_a_SOURCES)

  I hope this helps.
