--- Comment #1 from Andreas Schwab <schwab@linux-m68k.org> ---
There is no linkage conflict here.  The definition inherits the internal
linkage of the preceding declaration, so the resulting linkage is internal. 
See 6.2.2 #4 and #5.  Don't confuse the concept of linkage with storage-class
specifiers.
