State-Changed-Why:
Compiling your testcase with gcc 3.0 yielded the following
compilation error:
b.cc: In function `int main()':
b.cc:5: invalid `asm': operand number missing after %-letter
b.cc:5: invalid `asm': operand number missing after %-letter
If I changed the __asm__ line in your code to:
__asm__ __volatile__ ("movl %%eax,%%eax");
Then it compiled without problem.
Please see http://www.linuxassembly.org for a good tutorial
on the asm syntax.
