This is a good point! With the correct include path I get a working,
self-compiled amForth. Further I removed the -im32def.inc. The file is
included in the amForth sources anyway.

Thank you.

Now I want to take the second step, build for ATmega2560. I use nearly
the same avrsam2 command line, but changed the include path from
     amforth-6.9\avr8\devices\atmega32
to
     amforth-6.9\avr8\devices\atmega2560

avrasm2.exe -fI -o my2560.hex -e my2560.eep -S my2560.tmp -W+ie
-I"amforth-6.9\avr8" -I"amforth-6.9\avr8\devices\atmega2560"
-I"amforth-6.9\appl\arduino" -I"amforth-6.9\common" -d
"Debug\my2560.obj"  "main.asm"  -I "D:\Program Files
(x86)\Atmel\Studio\7.0\toolchain\avr8\avrassembler\Include"

Now I get several errors like:
error: Overlap in .cseg: addr=0x1f000 conflicts with 0x1f000:0x1f396
error: Overlap in .cseg: addr=0x1f001 conflicts with 0x1f000:0x1f396
...
error: Overlap in .cseg: addr=0x1f03e conflicts with 0x1f000:0x1f396

Shouldn't this compile out of the box?
I am also curious about this range 0x1f000:0xf1396.

Best regards,
Helge
