AVB My near TODO is to:
AVB - detect redefinition of env variables (and replace definition).
AVB - add environment before each INSTALL=.

 BTW, forget to mention. Some years ago I report about BUG in
ChildEnv(), which wrongly handles empty environment. And, yes, this is easy
to see: run some program through INSTALL= (in current FD) and review its
environment.

[Freedos-kernel] CONFIG.C ANNOYANCE

2004-06-23 Thread tom ehlert 
RANTMODE

I'M HIGHLY DISAPPOINTED TO FIND THAT SOME FORMERLY
WORKING CODE DOESN'T WORK ANYMORE; 

I'M IN PARTICULAR DISAPPOINTED AS 
THIS CODE WAS ONLY CHANGED TO SAVE SOME 20 BYTE OF 
INIT CODE. WELL - THIS SAVES 20 BYTE, BUT COSTED 
ME A MONTH TO DISCOVER - AND AN ADDITIONAL HOUR TO FIX.

TO ALL OPTIMIZERS: HANDS OFF. GO PLAY SOMEWHERE ELSE.


/RANTMODE


UWORD GetBiosKey(int timeout)
{
  iregs r;

  ULONG startTime = GetBiosTime();

  if (timeout = 0) do
  {
r.a.x = 0x0100; /* are there keys available ? */
init_call_intr(0x16, r);
-if ((unsigned)(GetBiosTime() - startTime) = timeout * 18u)
+if ((unsigned)(GetBiosTime() - startTime)  timeout * 18u)
  return 0x;
  }
  while (r.flags  FLG_ZERO);

  /* key available or blocking wait (timeout  0): fetch it */
  r.a.x = 0x;
  init_call_intr(0x16, r);
  return r.a.x;
}
