Summary: Interrupt routine prologue vars not declared

Initial Comment:
In the attached code when I try to compile it gives me
the following error:

mono[ir_dongle]$ make
sdcc -V -mpic14 -p16f84 -o ir_dongle.o ir_dongle.c
Processor: 16f84
+ "/usr/local/bin/sdcpp" -nostdinc -Wall -std=c99
-DSDCC=1 -DSDCC_MODEL_SMALL -DSDCC_pic14 -D__pic14
-I"/usr/local/bin/../share/sdcc/include/pic14"
-I"/usr/local/share/sdcc/include/pic14"
-I"/usr/local/bin/../share/sdcc/include"
-I"/usr/local/share/sdcc/include"  "ir_dongle.c" 
+ "gpasm" -c "ir_dongle.asm"
ir_dongle.asm:85:Error [113] Symbol not previously
defined (WSAVE).
ir_dongle.asm:89:Error [113] Symbol not previously

ir_dongle.asm:91:Error [113] Symbol not previously

ir_dongle.asm:107:Error [113] Symbol not previously

ir_dongle.asm:108:Error [113] Symbol not previously
defined (WSAVE).
make: *** [ir_dongle.o] Error 1

As you can see for some reason the variables in the
prologue and epilogue of the interrupt routine are not
declared.

Here is the sdcc version:

mono[ir_dongle]$ sdcc --version
SDCC :
mcs51/gbz80/z80/avr/ds390/pic16/pic14/TININative/xa51/ds400/hc08
2.4.7 #916 (Dec 28 2004) (UNIX)

I tryied to skip the bug by changing the isr to a naked
function:

static char ssave, wsave; 
static void interrupt_service_rutine () interrupt 0 _naked
{
  _asm
    movwf _wsave
    movf STATUS,w
    movwf _ssave
    _endasm;
  if (!IR_RX)
    SET_IR_RX_DOWN;
  _asm
    movf _ssave,w
    movwf STATUS
    movf _wsave,w
    retfie
    _endasm;
}

And now the error is:

mono[ir_dongle]$ make
sdcc -V -mpic14 -p16f84 -o ir_dongle.o ir_dongle.c
Processor: 16f84
+ "/usr/local/bin/sdcpp" -nostdinc -Wall -std=c99 -DSDCC=1
-DSDCC_MODEL_SMALL -DSDCC_pic14 -D__pic14
-I"/usr/local/bin/../share/sdcc/include/pic14"
-I"/usr/local/share/sdcc/include/pic14"
-I"/usr/local/bin/../share/sdcc/include"
-I"/usr/local/share/sdcc/include"  "ir_dongle.c" 

ir_dongle.c:26: syntax error: token -> '_naked' ; column 58
ir_dongle.c:32: error 103: code not generated for
'interrupt_service_rutine' due to previous errors
make: *** [ir_dongle.o] Error 1

So naked functions are also broken.
