re PR ada/26315 (ACATS failures c43208b c85006a c85006d cd92001)
2006-02-17 Eric Botcazou <botcazou@adacore.com> PR ada/26315 * utils2.c (find_common_type): If both input types are BLKmode and have the same constant size, keep using the first one. * bindgen.adb: (Gen_Versions_Ada): Revert previous workaround. * decl.c (gnat_to_gnu_entity): Only check TREE_OVERFLOW for a constant. * misc.c (gnat_handle_option): New case for -Woverlength-strings.
