Summary: Wine logs too verbose, quieter fixme's needed

The bug report contains, among other things, this suggestion:

Which suggests to me that the macro(s) could be modified to:
1. Use a local code block to declare a static flag variable.
2. Check that variable for zero (the default initial value IIUC)
3. and if it is zero, set the flag non-zero and print the message.

There is a short race where different threads might see the zero
value. If that happens, the message would be printed more than
once. I believe that is acceptable because the alternate is to
create a critical section, which is over-kill.

That would limit ALL fixme's to one printing. The bug report
mentioned variable information that might be included but implied
that any such information is more properly included in a 'trace'.
