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.
