-Wstrict-prototypes and void foo () {}

[Doug Evans]

The docs for -Wstrict-prototypes say

  Warn if a function is declared or defined without specifying the
  argument types.  (An old-style function definition is permitted without
  a warning if preceded by a declaration which specifies the argument
  types.)

I wonder if an exception to the "if preceded ..." clause can be made
for function definitions with no arguments.

Having to go and change lots of function definitions from

void
foo ()
{
  // mumble ...
}

to

void
foo (void)
{
  // mumble ...
}

is a pain _and_ an eyesore.
