Fixes to build emulators, ass, int on OpenBSD
 2018-06-20 22:30:01 +02:00
David Given 698613cd7d Turns out that the compiler needs access to the libpc headers too; refactor

contents of the register.
 2018-06-16 22:55:23 +02:00
David Given 5d7cdd2c67 Fix a setcr0 bug which was trashing the condition register; some system
