Re: [PATCH] glibc 2.7 compilation failure with GCC 4.2.x due to 486+-specific memmove() redeclaration and _FORTIFY_SOURCEry

I don't see how to make it go away, personally. It should turn up on any
platform that uses sysdeps/i386/i486/bits/string.h, as far as I can see.

I configured this particular platform on a PIII with this shell script:


export CFLAGS="-O2 -march=native -pipe"
export LDFLAGS=""

$CONFIGURE --build=i686-pc-linux-gnu "$@"

( is the default specs file generated by GCC 4.2.x:
otherwise, the default (customized) specs file on my site turns on
--build-id and --as-needed by default at link time, and the latter at
least is bad for the glibc testsuite. I have patches to allow glibc to
build with a default-on --build-id, if you want them, but they're so
trivial I thought nobody would care...)

This bug isn't a local patching thing: I see it with a pristine 2.7
