--- Comment #2 from Daniel Richard G. <skunk at iskunk dot org> 2012-05-02 15:57:24 UTC --- (In reply to comment #1) > Is this problem also present in more recent Solaris releases? It's gone as of Solaris 10 (the macros have the necessary casts), but I don't have a 9 system to check. Can a fixinclude go in, just so that 4.7 can have reasonably complete -Werror support for Solaris 8? No previous version of GCC is going to have that.
