Consider the following one-liner:
int func(int foo, int (*fn)(int foo));
Current g++ complains about shadowing, which seems incorrect to me:
~/tmp>g++ -c -W -Wall -Wshadow bug.cc
bug.cc:1: warning: declaration of 'int foo' shadows a parameter
bug.cc:1: warning: shadowed declaration is here
Curiously, no warning is generated by g++ 4.3.
gcc 4.4 and 4.3 don't produce the warning either.
