[Bug c/29521] New: Confusing warning for return with expression in function returning void

[muntyan at tamu dot edu]

Consider the following code:

void func () 
{
}

void func2 ()
{
    return func ();
}

gcc -pedantic correctly warns about "return func();", but the warning text is
very confusing:
   'return' with a value, in function returning void
It talks about "value" where there is no value involved.
It took me a while to understand what exactly is wrong. Warning says "value",
so I obviously checked signatures first; then I looked for a problem with
includes; then I asked in comp.lang.c.

It would be better if gcc said something like
   'return' with an expression, in function returning void
or
   ISO C forbids ...

The latter would be the best, I guess.
