Summary: Multiple definitions of _PORTB

Initial Comment:
The following program causes sdcc to allocate _PORTB to
address 
0x2d as well as its hardware address (so the assembler
chokes).

#include "16f627.h"

int main() {
    return PORTB & 0xf0;
}

A workaround is to assign the value of PORTB to a
temporary and operate on that.

$ sdcc -p16f627 -I../include -DTARGET_16f627 sdcc-bug1.c
Processor: 16f627

Works with SDCC 2.5.1 #1053. I will close this in less than
two years time if nobody disagrees ;-)
