--- Comment #21 from David Malcolm <dmalcolm at gcc dot gnu.org> ---
gcc 8 now underlines the pertinent parameter (as of r253411 and r253096 for
C/C++ respectively):

C:

$ ./xgcc -B. -c t.c
t.c: In function ‘docall’:
t.c:8:3: warning: passing argument 3 of ‘callf’ from incompatible pointer type
[-Wincompatible-pointer-types]
   f);
   ^
t.c:3:22: note: expected ‘int (*)(double *)’ but argument is of type ‘int
(*)(int *)’
 int callf (int, int, int (*)(double *));
                      ^~~~~~~~~~~~~~~~~

C++ (which also now underlines the pertinent argument, as of r256448):

$ ./xg++ -B. -c t.c
t.c: In function ‘int docall()’:
t.c:8:3: error: invalid conversion from ‘int (*)(int*)’ to ‘int (*)(double*)’
[-fpermissive]
   f);
   ^
t.c:3:22: note:   initializing argument 3 of ‘int callf(int, int, int
(*)(double*))’
 int callf (int, int, int (*)(double *));
                      ^~~~~~~~~~~~~~~~~
