Thanks for the report.  As you point out, this is not a bug in autoconf, but in Avast, and it's not worth making autoconf try to work around overactive virus checkers.

I tried to compile mpeg4ip- on mingw32, and Avast barked at a.exe being some virus.

Well, a.exe is just a

int main(void){ return 0; }


I did all sorts of tampering with Avast to deactivate it, but it was still barking.

After some time I modified the configure script so that the a.exe source code be:

main ()

  int i = 3;
  float c = b +i;
  i = (int)c;
  return i;

with this, the a.exe was no longer detected as a virus, and I could progress a bit more in the configure script.

OK, this is not really a bug of Autoconf, but still I think that it is good for you to know.
