This is why I put this definition in the general file in wordsize-32.
I guess it's best to have a Hurd-specific version since a) other
Unices support this model and b) Hurd will hopefully support this as
well sometime in the future.
OK, thanks, for the clarification.
Here is the Hurd-specific file.

* sysdeps/mach/hurd/i386/bits/environments.h: New file. Define
_XBS5_ILP32_OFFBIG to -1. We don't support this environment yet
for the Hurd.
