Summary: trivial program linking fails for 12f675

Initial Comment:
under: 
sdcc -v                           
SDCC : mcs51/gbz80/z80/avr/ds390/pic16/pic14/TININative/xa51/ds400/hc08 2.6.0 #4309 (Nov 29 2006) (UNIX) 

this progam (trivial):
#define __pic12f675
#include <pic12f675.h>
void spin256 () { char i ; for ( i=255; i != 0; i--) {} }
void main (void) { spin256 (); }

fails to link:
sdcc  --debug   --verbose  -mpic14 -p12f675 main.c
Processor: 12f675
sdcc: Calling preprocessor...
sdcc: Generating code...
sdcc: Calling assembler...
main.asm:162:Warning [230] directive ignored when debug info is disabled

sdcc: Calling linker...
message: using default linker script "/usr/local/gputils/share/gputils/lkr/12f675.lkr"
error: linker script has no definition that matches the type of section "udata_main_0"

This is reproducable under FreeBSD 6 and OS X.4.
gpasm 0.13.4b correctly builds 12f675 assembly projects in this installation.

Switching sdcc to the 16f684 target produces working output.

After calling "sdcc -c  -p12f675 main.c" and  "sdcc -c  -p16f864 main.c" I found that they both generated almost identical .asm files.

I'm very exicted about having an OSS compiler for little targets; I'll be happy to provide support for  developers.
