In general that's true from the programmer's viewpoint. But this does
not apply to adding language details because there is no 'first make it
work'. Why obscure important implementation details if the only benefit
is

From the point of view of FPC, there should not be a big problem.
The C library, this is another matter. I am not sure that it

I'm curious: who needs more than 13 different image interpolations?
13 different users, of course. ;)
That was a rhetorical question, wasn't it?

IIRC Turbo Pascal only allowed you to access s[0] when range checking

Hi,
suppose I need some threadvars inside dynamically allocated objects to keep
track of the number of calls to certain methods. Basic requirement is to keep
track of recursive calls per thread, so I tried implementing that with thread
vars. Only problem: How do I initialize them? I can't do
Hi,
I think that thread variables are automatically initialized to zero. So
you just need to use them in such a way that zero is the desired start
value.
Hmm, yes. I just checked the sourcecode and indeed, for Win32 and Unix at least
the threadvars are indeed initialized to zero. That would

Hmm, didn't the x87 copro stack had 7ish registers? And recursive you say?
