commit 7b4ab0895b51f21d9f15581d2407861bac986231
Author: Andy Wingo <address@hidden>

    Inline definition of SIZEOF_SCM_T_BITS
    
    * libguile/_scm.h (SIZEOF_SCM_T_BITS): Remove definition.
    * libguile/conv-integer.i.c (SCM_TO_TYPE_PROTO, SCM_FROM_TYPE_PROTO):
    * libguile/conv-uinteger.i.c (SCM_FROM_TYPE_PROTO):
    * libguile/gc.c (DEFAULT_INITIAL_HEAP_SIZE):
    * libguile/hashtab.c:
    * libguile/loader.c:
    * libguile/socket.c:
    * libguile/vm-engine.c (VM_NAME): Use SIZEOF_UINTPTR_T instead of
      SIZEOF_SCM_T_BITS.
