No, please keep the message.  That GNU ld doesn't error out in this case 
is a side-effect of GCC using common symbols.  If it wouldn't then also ld 
would error.  Try compiling the above with -fno-common and GCC and you'll 
see it.

It would also error out if you would initialize both definitions.  So, 
please revert.


Ciao,
Michael.
