Thanks Frieder,
I will try that later on, I was making the correlation between the final
output file .hex size to the actual size of the object code. The object
code size is estimated and put at the end of the generated .asm file Doh!!!!
However, there is a significant difference between the two code sizes.

Comparing the size of Intel hex files is probably
not what you want, because it only gives an estimate
of the code size.
*If* the extra '.' in line 93 is removed your code.c results in
a hex file code.hex of 820 bytes.
you can reduce this with
> packihx code.hex >t.hex
to 804 bytes.
or with srec_cat (srecord.sf.net)
> srec_cat code.hex -intel -o t.hex -intel
to 712 bytes.
or with extra options on the command line
> srec_cat code.hex -intel -o t.hex -intel_hex_16 -Line_Length 127
to 648 bytes.
and just for the record also increase with
> srec_cat code.hex -intel -o t.hex -intel -Line_Length 20
to 1444 bytes.
Compare the used addresses in the listing files of
SDCC and PCW instead?
0x008e corresponds to 286 bytes = 2 bytes * (0x8e+1)
A 175 bytes intel hex file generated by PCW would probably
be equivalent to not more than about 80 bytes of code which
would be an almost incredibly good result.
(There are 42 assignments, 7 increments/decrements, an
IRQ and 11 conditions in the c code and a pic opcode
does not fit in a byte.)
Eventually 175 byte should be compared to 286 byte?
Greetings,
Frieder
