annotate src/g23m-fad/ra/ra_shm.c @ 205:81f5c4ca1fb3
mmiDialogs.c: make dialog_info() static
The function in question was first declared as static, then defined
as non-static, which should be considered invalid C. Given that
this function is not referenced from any other modules and appears
to have been intended as static, make it so.
