One step further.

There is one other difference which I dismissed before, as after I 
quoted verbatim the command-line I used, I assumed that you used the 
same flags as I did.  Now I see that that wasn't the case.

With the pre-compiled native MinGW GCC 3.4.5, as well as with the 
self-built cross-compiled 3.4.5 hosted on Cygwin, the error only occurs 
when the -pedantic flag is used.  You must've compiled the code without 
that flag, I've compiled with it, that's why we had different results. 
For the record, when I remove that flag from the command-line, the 
compiler doesn't complain.

The newer versions (4.x series) of GCC though, getting less permissive 
and more aggressive about strictly implementing the requirements of the 
language standard, issue the error even without the -pedantic flag.

I'll be (time permitting) looking into this further.

Best regards.
