--- Comment #11 from Florian Weimer <fw at gcc dot gnu.org> --- (In reply to David Brown from comment #9) > Could -Wstrict-prototypes be added to -Wall, or even considered enabling by > default? The next C standard will make "void foo()" mean the same as "void > foo(void)", like in C++, which makes the scope for confusion high. I think the churn from changing void foo() to void foo(void) to avoid the warning is too high, and unnecessary for the upcoming C language change. A more target warning could make sense, though.
