Same thing a few lines further down in the same file:

trunk/libgcc/soft-fp/op-common.h:913:10: warning: this statement may fall
through [-Wimplicit-fallthrough=]

Source code is

    case _FP_CLS_COMBINE (FP_CLS_INF, FP_CLS_NAN):      \
    case _FP_CLS_COMBINE (FP_CLS_ZERO, FP_CLS_NAN):     \
      R##_s = Y##_s;                    \
                                \
    case _FP_CLS_COMBINE (FP_CLS_NORMAL, FP_CLS_INF):   \
    case _FP_CLS_COMBINE (FP_CLS_NORMAL, FP_CLS_ZERO):  \

And a third case in the same file, line 1200:

    case _FP_CLS_COMBINE (FP_CLS_NORMAL, FP_CLS_ZERO):  \
      FP_SET_EXCEPTION (FP_EX_DIVZERO);         \
    case _FP_CLS_COMBINE (FP_CLS_INF, FP_CLS_ZERO):     \
