Summary: Incorrect code when accessing xdata

Initial Comment:
The attached C file produces incorrect code when compiled on 2.8.0 using
sdcc -c test.c

test1 stores 0x01 in location 0xf000 (incorrect)
test2 stores 0x03 in location 0xf000 (correct)
They should be equivalent. Supplied headers from TI use the (*(xdata char*) XXXX) format.

Correction to the above:
test1 stores 0x02 in location 0xf000 (incorrect)
test2 stores 0x03 in location 0xf000 (correct)
This also happens on  2.8.9 #5397 (Mar  1 2009)  (ie. RC1)
Tested using s51 also from RC1.
