duplicate #define in gcc/config/sparc/sp64-elf.h

To: gcc-bugs at gcc dot gnu dot org
Subject: duplicate #define in gcc/config/sparc/sp64-elf.h
From: Alexey Mahotkin <alexm at jet dot msk dot su>


There should be 

#undef DWARF_DEBUGGING_INFO

before the

#define DWARF_DEBUGGING_INFO

in the sparc/sp64-elf.h.  Otherwise, the following annoying warning is
emitted when compiling for target `sparc64-sun-elf'.


/tmp/alexm/gcc-3.0/gcc/config/sparc/sp64-elf.h:115: warning: `DWARF_DEBUGGING_INFO' redefined
/tmp/alexm/gcc-3.0/gcc/config/elfos.h:68: warning: this is the location of the previous definition
