I'm using: ac++ 1.0pre4 svn (Mar 29 2008).

I tried your example with the following commands:

 > ac++ -p. -c main.cc -I . -a Led.ah -o main.acc
 > gcc -o prog -x c main.acc

No errors occurred. How did you weave the code? I'll definitely try it 
also with a newer ac++, maybe something is broken between March and July.
