I am saying that no warning should warn for things that are valid C but

That could be (I disagree, but that's another debate), but the question was
whether allowing this case would improve the warning or not. If you change it
to allowing such a case, you also make
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=87038
--- Comment #12 from Segher Boessenkool ---
That is not a reason to have the warning in C, not without some "-Wc++-compat"
or similar; and in C++ it should be an error you say, not a warning at all.
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=87038
--- Comment #11 from Steinar H. Gunderson ---
It is also not legal (side effects or not) when compiling as C++, which is one
of the reasons for having this warning.
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=87038
--- Comment #10 from Segher Boessenkool ---
The initialisation (the call to f1) could have a side effect, but the
a==1 case skips that. GCC is right to warn here in my opinion.
