--- Comment #21 from Sean McGovern <gseanmcg at gmail dot com> 2011-01-04 18:11:09 UTC --- Why not introduce a warning for 4.6 that it is linking against this object file and that any other libraries alongside that are not tested against C99 may experience side effects, with eventual deprecation (of the warning) later on in 4.7 or 4.8? Is this appropriate to do inside collect2?
