The .ac fragment is:

| # Enable -Werror in bootstrap stage2 and later.
| AC_ARG_ENABLE(werror,
| [AS_HELP_STRING([--enable-werror],
|                 [enable -Werror in bootstrap stage2 and later])], [],
| [if test -d ${srcdir}/gcc && test x"`cat $srcdir/gcc/DEV-PHASE`" = xexperimental; then
|   enable_werror=yes
| else
|   enable_werror=no
| fi])
| case ${enable_werror} in
|   yes) stage2_werror_flag="--enable-werror-always" ;;
|   *) stage2_werror_flag="" ;;
| esac
| AC_SUBST(stage2_werror_flag)

This was added on Wed Mar 24 22:08:39 2004 +0000. The `'
file uses it since it was added to GCC on Thu May 5 01:47:47 2011 +0000.

Not sure:

gcc20: g++ (Debian 4.4.5-8) 4.4.5
gcc76: g++ (Debian 4.4.5-8) 4.4.5
pluto: g++ (Debian 4.9.1-1) 4.9.1

However, the "pluto" box also fails, and it's GCC is about up-to-date.
