Silence all casting errors by using casting functions. * src/cc.c (cast_charp_to_scmp, cast_charp_to_scmpp, cast_voidp_to_charp, cast_scmp_to_long, cast_scmp_to_charp): New function. * src/m2.c (cast_charp_to_scmp, cast_charp_to_scmpp, cast_voidp_to_charp, cast_scmp_to_long, cast_scmp_to_charp): New function. * include/mes/mes.h: Declare them. (struct scm): Add car_value, cdr_value, function. (g_continuations): Change to long. * src/mes.c: Silence all casting errors by using casting functions.
