some questions ...

Hi Sven, hi everybody,

> Somebody have found the C2PAS converter?

I have never seen such a thing - only the p2c.

> Why is the boolean type internal so big (Integer) ?

I could not reproduce this bug.  Var B: Boolean; writeln ( Sizeof ( B ) )
yields 1 on my machine.

> Boolean should only use a bit - yes thats stupid,

It's not stupid at all.  One day, GPC will actually pack `packed
arrays' of Boolean or `packed records' containing Booleans and
Integer subranges, then each Boolean will only get a single bit.

> Why crashed the compiler very often?

If we knew the answer, the compiler wouldn't crash any more, sigh.

Please collect the source which makes the compiler crash, so we
can correct the bug.

I agree, but I have no idea how to implement this with a Bison
parser (I am not so experienced with Bison).  Somebody has?

This is a bug in GPC and must be fixed.  For the moment, use (*$W-*)
to switch off annoying warnings, use (*$W+*) to switch them on again.

By the way, Sven, your DosFile Unit does not only work around a
bug, but it also implements some missing functions such as BlockRead,
BlockWrite, and IOresult.  Gut gemacht! :-) :-)

Shall I put it into a gpc-2.7.2/contrib directory?  Somebody out there
willing to make it portable?  It should not be too difficult to 
translate the DOS system calls to UNIX system calls.
