It's documented as:
‘-Wmissing-parameter-type (C and Objective-C only)’
A function parameter is declared without a type specifier in
K&R-style functions:
void foo(bar) { }
This warning is also enabled by ‘-Wextra’.
What this doesn't say is that this has been subsumed by -Wimplicit-int
in C99 and later language modes.
Maybe we can tweak things such that -Wmissing-parameter-type controls
declarations only in C99 and later language modes, and turn just that
into a permerror. But the situation is confusing enough already, which
is why I opted for the separate warning.
Thanks,
Florian
