buildfailure in expr.c on darwin

[Andreas Tobler <a dot tobler at schweiz dot ch>]

Hi,

I get the following failure on darwin with the changes from last night.
I can't figure out where the related change comes from.
I produced a .i file and tried to find the failing reason. Below I
copied also the part from the .i file which I think is related to. Any
hints on how to find the reason?

Thanks
Andreas

BTW, is gcc.gnu.org down?
