------- Comment #1 from burnus at gcc dot gnu dot org 2008-04-17 08:50 ------- Can you try: -Wconversion Warn about implicit conversions between different types.
It might be a bit verbose as it, e.g., also warns for "complex(8) = real(8)", which has no conversion problem, but otherwise it is ok. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=35962
