3.4 build problem on sh4: warning: "ASM_PREFERRED_EH_DATA_FORMAT"redefined


Compiling a gcc-3.4 snapshot for the first time, I got the following warning:

/xx/sh4-unknown-linux-gnu/gcc-3.4-20030813-glibc-2.3.2/gcc-3.4-20030813/gcc/config/sh/linux.h:44:1: warning: "ASM_PREFERRED_EH_DATA_FORMAT" redefined
In file included from tm.h:6,
                 from /xx/sh4-unknown-linux-gnu/gcc-3.4-20030813-glibc-2.3.2/gcc-3.4-20030813/gcc/gengenrtl.c:26:
/xx/sh4-unknown-linux-gnu/gcc-3.4-20030813-glibc-2.3.2/gcc-3.4-20030813/gcc/config/sh/sh.h:3484:1: warning: this is the location of the previous definition

The two definitions are different:
config/sh/linux.h:
    44  #define ASM_PREFERRED_EH_DATA_FORMAT(CODE, GLOBAL)                      \
    45    (flag_pic                                                             \
    46      ? ((GLOBAL) ? DW_EH_PE_indirect : 0) | DW_EH_PE_pcrel | DW_EH_PE_sdata4 \
    47     : DW_EH_PE_absptr)

config/sh/sh.h:
   3482 /* We have to distinguish between code and data, so that we apply
   3483    datalabel where and only where appropriate.  Use textrel for code.  */
   3484 #define ASM_PREFERRED_EH_DATA_FORMAT(CODE, GLOBAL) \
   3485  ((flag_pic && (GLOBAL) ? DW_EH_PE_indirect : 0) \
   3486   | ((CODE) ? DW_EH_PE_textrel : flag_pic ? DW_EH_PE_pcrel : DW_EH_PE_absptr))

which makes me wonder if the right one is being used.

Thanks,
Dan
