Reading specs from /usr/local/packages/gcc-3.3/lib/gcc-lib/sparc-sun-solaris2.8/3.3/specs
Configured with: ../configure --prefix=/usr/local/packages/gcc-3.3 : (reconfigured) ../configure --prefix=/usr/local/packages/gcc-3.3 --disable-multilib

>Description:
extern "C" {
  void g( void *);
};

struct X {
  static void a() { }
};

extern "C" void f() {
  void *a = (void*)(X::a);
  void *b = reinterpret_cast<void*>(X::a);
  void *c = reinterpret_cast<void*>(&f);

}


The the (void*)line compiles, while the reinterpret_cast lines generate:
fp4.C:15: error: ISO C++ forbids casting between pointer-to-function and 
   pointer-to-object
fp4.C:16: error: ISO C++ forbids casting between pointer-to-function and 
   pointer-to-object

I would expect all three lines to fail.
