* On UNIX systems, the collector will scan the area between DATASTART
* and DATAEND for root pointers.
*
* DATAEND, if not &end.
* DATAEND, if not `end' where `end' is defined as ``extern int end[];''.
* RTH suggests gaining access to linker script synth'd values with
* this idiom instead of `&end' where `end' is defined as ``extern int end;'' .
*
* ALIGN_DOUBLE of GC_malloc should return blocks aligned to twice
* the pointer size.
