Summary: Compilation failing

Initial Comment:
After compiling a C code, I get an error message from
the assembler claiming that a register "s0xF7" is not
defined, plus some claims that the PSAVE, SSAVE and
WSAVE registers change on 2nd pass. Follows the command
issued to start the compilation and the source code.

otavio@otavio:~/pic$ sdcc -v
SDCC : pic16/pic14 2.5.0-pre1 #1018 (May  1 2005) (UNIX)

include <p16f84.h>

typedef enum { LEFT_MOTOR = 0, RIGHT_MOTOR = 2 } t_motor;
typedef enum { FORWARD = 0x01, BACKWARD = 0x02 }
t_direction;

static unsigned char porta_motor_mask(t_motor motor);

void turn_motor_on(t_motor motor, t_direction direction) {
    PORTA = (PORTA & porta_motor_mask(motor)) |
(direction << motor);
}

void turn_motor_off(t_motor motor) {
    PORTA &= porta_motor_mask(motor);
}

unsigned char porta_motor_mask(t_motor motor) {
    switch (motor) {
        case LEFT_MOTOR:
            return 0xFC;
            break;
        case RIGHT_MOTOR:
            return 0xF3;
            break;
    };
    return 0xFF;
}

int
main(void) {
    while (1) {
        if (PORTA & 0x10) {
            turn_motor_on(LEFT_MOTOR,FORWARD);
        } else {
            turn_motor_off(LEFT_MOTOR);
        }
    }
}

I first ran into this issue with:
$ sdcc -v
SDCC : pic16/pic14 2.4.0 (Apr 29 2005) (UNIX)
$ sdcc -mpic14 -p16f84 -o test -Iinclude/ src/control.c
Processor: 16f84
test.asm:105:Error [113] Symbol not previously defined
(s0x7F).
test.asm:206:Error [113] Symbol not previously defined
(s0x7F).
