Hello
This patch fix error on 'gnulib' library required to build 'grep' 
package on GNU/Hurd.

The error was fixed on upstream, this is the report:

Thanks

Looks like we missed this ‘core-updates’ cycle.  :-/

To apply it without triggering a full rebuild, you could instead add a
phase that invokes ‘patch’ to apply it, only when the cross-compilation
target or system is GNU/Hurd.

Like:

  ,@(if (gnu/hurd?)
        `((add-before 'configure 'patch …))
        '())  ;nothing

Could you try that?

Also please avoid reindenting the package at the same time as it makes
the patch a bit noisier.  :-)

Thanks,
Ludo’.

Even though this would work, maybe we should wait for the next
core-updates circle in order to avoid more (if (hurd)..) patches.

Rene WDYT?

Yes, we can wait for the next cycle.

Sure, either way is fine with me.

Hello Rene,

I pushed the patch to core-updates.

more (if (hurd ...)) patches does also make it easier to merge in
changes for those not using hurd when the time comes, and it allows
those actively using hurd to make changes to more low-level packages
without worrying about how it affects the other architectures/kernels.

Yes I agree, but here we have an upstream grep patch, which in the next
version will be in. No need to add unnecessary if statements.

Also I think it's a good idea to keep things kernel agnostic as much as
possible.
