* include/jvm.h (gcj::verifyClasses): Declare.
* link.cc (gcj::verbose_class_flag): Moved.
* prims.cc (gcj::verifyClasses): Define here.
(gcj::verbose_class_flag): Move definition here.
(_Jv_Linker::wait_for_state): Don't call verify_class
if gcj::verifyClasses is not set.
* gij.cc (main): Set gcj::verifyClasses when '-noverify' is given.
2005-05-12 Aaron Luchko <aluchko@redhat.com>
* gij.cc (main): Recognize '-verify', '-noverify', and
'-verifyremote'
2005-05-12 Aaron Luchko <aluchko@redhat.com>
