Change History (most recent first):
<SM11> 11/22/93 pdw Rolling in from <MCxx>.
<SM10> 11/21/93 pdw Removed IllegalInstruction and UnimplentedATrap procedures.
<SMG3> 9/29/93 chp Include ACAM.h if necessary.
<SMG2> 9/22/93 chp Add a TestFor for Grand Central.
<SM8> 10/14/93 pdw <MC> roll-in.
<SM7> 8/13/93 pdw Changed TestFor_Orwell to TestFor_OrwellExists
<SM6> 7/17/93 pdw Added VMRunning routine header.
<SM5> 5/5/93 PW Adding IllegalInstr() and UnimplementedATrap() functions.
<SM4> 5/5/93 PW Converted names to meanies-friendly names. Updated with latest
from Ludwig stuff.
<LW5> 4/14/93 DCB Added prototype for CallOldXPT
<LW4> 2/17/93 PW Rolled in some of the PDM changes to make it easier to remain
sane.
<SM3> 4/8/93 DCB Added glue for TestForDJMEMC and TestForOrwell
<SM2> 1/31/93 PW Update from the latest of Ludwig. Also changes required for PDM
(will update Ludwig with these as needed myself).
<LW3> 1/27/93 PW Changed VMEnableUserCode prototype to return void again because
that last fix was a bogus way of doing it.
<LW2> 1/12/93 DCB Changed prototype for VMEnableUserCode.
