I only attempted to understand the "USE, ONLY" construct.
There is a struct gfc_use_rename that is used in gfc_match_use()
to build a list of symbols as they are read.   This is the
root of the problem with "USE, only : a => z, b => z".  By the
time "b => z" is parsed, z has already been renamed to a and
so it no longer exists.  I think you want to be around line 504
in module.c.
