I tried to repro this today and here are my results:
lp:~ubuntu-desktop/lightdm/ubuntu/
quantal - real h/w - amd64 - builds fine: gcc version 4.7.0 (Ubuntu/Linaro 4.7.0-13ubuntu1)
quantal - real h/w - i386 - builds fine: gcc version 4.7.0 (Ubuntu/Linaro 4.7.0-13ubuntu1)
quantal - pbuilder - i386 - builds fine: gcc version 4.7.0 (Ubuntu/Linaro 4.7.0-13ubuntu1)
lp:lightdm (trunk)
quantal - real h/w - amd64 - builds fine: gcc version 4.7.0 (Ubuntu/Linaro 4.7.0-13ubuntu1)
quantal - real h/w - i386 - builds fine: gcc version 4.7.0 (Ubuntu/Linaro 4.7.0-13ubuntu1)
quantal - pbuilder - i386 - builds fine: gcc version 4.7.0 (Ubuntu/Linaro 4.7.0-13ubuntu1)
Therefore I am marking this invalid unless someone wants to re-open it. I know that gcc changed since this was filed, as did trunk for lightdm, and I assume some combo fixes this.
