Pointer arithmetic on void * pointers results in a GCC warning. Avoid the warning by casting the pointer to its actual type earlier in the function. sim/rx/ChangeLog: * mem.c (mem_put_blk): Rename parameter, add cast from parameter type to local type. Remove cast later in the function. (mem_get_blk): Likewise. * mem.h (mem_put_blk): Rename parameter to match definition. (mem_get_blk): Likewise.
