* config/tc-ppc.c (ppc_bb): Call SF_SET_PROCESS.
(ppc_eb): Likewise. Set the storage class to C_BLOCK, not C_FCN. (ppc_frob_symbol): Don't change C_BLOCK symbols to C_HIDEXT. * config/obj-coff.c (coff_frob_symbol): Don't call SA_SET_SYM_ENDNDX with the current symbol; call it with the next one. If OBJ_XCOFF, try to figure out whether the symbol is going to be dropped.
