They are smaller and faster because they take advantage of the pce CPU's block-copy instructions.
Also, made a small improvement to the common memmove(), so that it is similar to the pce version.

Changed the way that ld65 handles bad offset/start segment attributes, and reports memory area overflows.
1. Offset/start attributes within a memory area are ignored after an overflow.
2. If a previous segment ends past an offset/start address, then that address is not used.
3. Short map files were generated for memory overflows; now, they are generated for bad offset/start addresses, too.

Adjusted current working directory initialization on Apple and Atari.
Moving __cwd from BSS into INITBSS does of course ;-) not only impact the CBM targets but all targets with disk I/O support.
Note: Code using `__cwd-1` may trigger an ld65 range error because __cwd may end up at the very begining of a segment. As far as I see this is an ld65 bug which I'm not try to fix - at least here.
Oliver Schmidt [Wed, 14 Oct 2015 20:52:09 +0000 (22:52 +0200)]
Changed run location of INIT segment.
So far the INIT segment was run from the later heap+stack. Now the INIT segment is run from the later BSS. The background is that so far the INIT segment was pretty small (from $80 to $180 bytes). But upcoming changes will increase the INIT segment in certain scenarios up to ~ $1000 bytes. So programs with very limited heap+stack might just not been able to move the INIT segment to its run location. But moving the INIT segment to the later BSS allows it to occupy the later BSS+heap+stack.
In order to allow that the constructors are _NOT_ allowed anymore to access the BSS. Rather they must use the DATA segment or the new INITBSS segment. The latter isn't cleared at any point so the constructors may use it to expose values to the main program. However they must make sure to always write the values as they are not pre-initialized.

Adapted, to the c64 target, the INIT-segment overlay scheme from the apple2 targets.
When a program starts running, INIT is moved from one place to another place. Then, INIT's code is executed; and, the first place is re-used for variables. After the INIT code has finished, the second place can be re-used by the heap and the C stack. That means that initiation code and data won't waste any RAM space after they stop being needed.
