Alpine Linux:

  filesys.c: In function 'scm_sendfile':
  filesys.c:1405:16: error: assignment to 'off_t *' {aka 'long long int *'} from incompatible pointer type 'scm_t_off *' {aka 'long int *'} [-Wincompatible-pointer-types]
   1405 |     offset_ptr = SCM_UNBNDP (offset) ? NULL : &c_offset;
	|                ^
