Eliot Miranda uploaded a new version of VMMaker to project VM Maker:
http://source.squeak.org/VMMaker/VMMaker.oscog-eem.2879.mcz
==================== Summary ====================
Name: VMMaker.oscog-eem.2879
Author: eem
Time: 11 November 2020, 6:26:32.227544 pm
UUID: d024a598-2be9-4f62-a1fa-dd832d57dfd0
Ancestors: VMMaker.oscog-eem.2878
And linux doesn't pick up sys/types.h in cogit.c so type ceTryLockVMOwner using usqIntptr_t.
