Ok, was able to get rid of the "error: narrowing conversion of ..." at
the cross stage of gcc by adding:
var_append GCC_WRAPPER_APPEND " " "-Wno-narrowing" to the cross stage.
I am assuming that this does not show up in the native build, since no
one else has hit this error.
Patch attached.

Ok, now I have gotten all the way up to gcc stage 1.
