If this file

  static int foo();

  int foo() 
  {
	return 1;
  }

is compiled -Wall -c, no warning is issued regarding mismatched storage
class between the declaration and the definition.  The function is taken
to be static, as shown by nm on the result (`t' indicates static symbol
in SunOS nm):

  00000000 t _foo
  00000000 t gcc2_compiled.

Taking foo as static is OK, since the first external declaration
specifies static.  The Standard describes how the types must all match
up, but what does it say about storage classes? Should a warning be
issued? 

This is gcc 2.1 on Sun4 SunOS 4.1.2.
