1532 (INO_T_EQ): Define this (copied from cccp.c).
1533 (hack_vms_include_specification): Remove all calls and #if 0
1534 out the definition. It was being called incorrectly and at
1535 the wrong times. Until a VMSie can look at this, it's better

1647 The strategy we now use is to pre allocate the top_elt along
1648 with the EH context so that each thread has its own top_elt.
1649 This is necessary as the dynmanic cleanup chain is used on the
1650 top element of the stack and each thread MUST have its own.
