Can't build 2.20 for VxWorks with GCC 4.5.0 on Mac OS X Snow Leopard

[Simon Wright]

The build fails with

gcc -DHAVE_CONFIG_H -I. -I../../binutils-2.20/binutils  -I. 
-I../../binutils-2.20/binutils -I../bfd -I../../binutils-2.20/binutils/../bfd 
-I../../binutils-2.20/binutils/../include -I./../intl 
-DLOCALEDIR="\"/opt/gcc-4.5.0-i686/share/locale\"" 
-Dbin_dummy_emulation=bin_vanilla_emulation  -W -Wall -Wstrict-prototypes 
-Wmissing-prototypes -Werror -g -O2 -MT strings.o -MD -MP -MF .deps/strings.Tpo 
-c -o strings.o ../../binutils-2.20/binutils/strings.c
cc1: warnings being treated as errors
../../binutils-2.20/binutils/strings.c: In function ‘strings_file’:
../../binutils-2.20/binutils/strings.c:419:3: error: ‘stat64’ is deprecated

Recompiling just this file without -Werror works, of course.

The configuration command was

$ ../binutils-2.20/configure --prefix=/opt/gcc-4.5.0-i686 
--target=powerpc-wrs-vxworks

The C compiler was (from config.log)

configure:4029: gcc -v >&5
