When the target is an array, the address of the first member is
returned:
dmW->fmFormName is:  &(dmW->dmFormName[0])

similar:
 char buffer[32];
 printf("buffer at %p\n", buffer);

which is only a shortcut for:
printf("buffer[0] at %p\n", &buffer[0]);

No, removing deadcode must be enabled. You can use every compiler.
