[avr-gcc-list] Astudio source display

[Russell]

Hi all,

I'm using avr-gcc 3.0.3 and Astudio 4.05 with an at90s8535.
I can load the intel hex (ihex) file into astudio and
see the assembly code, but i can't get the C source to
display. Do i need to load a symbols file separately?
I've got all kinds of debugging options switched on:
  CFLAGS: -c -Wall -g -mmcu=at90s8535 -Wstrict_prototypes -mcall-prologues \
                              -Wa,-ahls=target.lst,-L
  LDFLAGS: -Wl,-Map,target.map

When i load target.hex (generated with avr-objcopy), astudio shows
the assembler code, but says:
  "Coordinator: The object file does not contain source code information."
