This is a recent regression on the 4.0 branch, 4.1 branch and mainline.
GCC 4.0.2 was not affected. We got the error message:
bug.cc:6: error: invalid function declaration
With GCC 3.4.5 the error message was:
bug.cc:6: error: `A<0>' specified as declarator-id
bug.cc:6: error: invalid function declaration
