Oh, in fact you're calling the C++ compiler, but reported it for Component=c

The wording is the same but location info is slightly different between the
two:

v.c: In function ‘main’:
v.c:7:10: error: void value not ignored as it ought to be
   return func();
          ^~~~~~
tmp$ g++ v.c
v.c: In function ‘int main()’:
v.c:7:15: error: void value not ignored as it ought to be
   return func();
               ^
