+ * Makefile.in (REAL_SOURCES): Added ecoff.c.
+ (REAL_HEADERS): Added ecoff.h.
+ (OBJS): Added ecoff.o.

+ data offset on reloc[0]->address rather than reloc[j]->address, so
+ that multiple relocs can affect different memory locations.
+
+ * write.c (chain_frchains_together, relax_and_size_seg,

+ the .subspace directive. Likewise for the section alignment.
+ Pass the current space to update_subspace and create_new_subspace.
+ (pa_spaces_begin): Only use space/subspace aliases if USE_ALIASES
+ is true. When not using aliases, create a BFD section for each
+ subspace encountered. When not using aliases replace the default

+ (create_new_subspace): When not using aliases each subspace has a
+ section/segment and subsegments are not needed, so set the subsegment
+ to zero.
