a) v1.5.1 has Altivec off by default when built for OS4
b) I've moved my detection code into libjpeg-turbo, so the env-var will now *only* be an override
This is a quick fix to stop NetSurf crashing when the URL is provided on the commandline without the URL keyword.
Passing options on the commandline will not work until this is fixed properly.
This will happen when attempting to open old 68k libraries with no separate interface file, but may also occur when the interface name or version doesn't exist (although the library version number _should_ prevent that)
I've never been entirely clear on what the correct approach here is, but OS4 has a feature where it will auto open/close a public screen for you. In this case, in the microseconds between unlocking that screen and attempting to close it, OS4 has already disposed of the screen and NetSurf has crashed, so we assume the owner will handle the closing instead.
Add some more debug:
It appears that some timer events are not being picked up, I can see in the log that something which should have been signalled is not being run.
Enabling the log appears to make the situation worse.
This is a hang-over from the old polling scheduler. I've modified it to use relative times and pass the callback along with the TimeRequest so events get executed in the order they arrive.
The list of events is still in a heap sorted by expected execution time, but this may need to change to something more efficient for random lookups.
TimerRequests are removed from the message queue by WaitIO() which is ultimately called when the event is taken off the heap.
The event on the top of the heap is _not necessarily_ the one which signalled us, though, and we should probably be handling this better.
The avoids situations were we threw away the length, only for
the caller to have to strlen the returned string.
Note, there seems to be a case of the amiga front end writing
beyond end of allocation. Added a TODO for now.
