[PATCH] GNU/Hurd target configuration

[PATCH] GNU/Hurd target configuration

[Thomas Schwinge]

[-- Attachment #1: Type: text/plain, Size: 6207 bytes --]

Hello!

Here is a patch to bring the target configuration for GNU/Hurd up to a
level so that GCC trunk is buildable for GNU/Hurd again (together with
other patches that are already available or are still to be written; see
my other posts).  This GCC does even ;-) produce working binaries.
Please discuss with the goal to have this eventually committed to the GCC
trunk.

No ChangeLog yet.

Please add the standard header including license info.  I would not be
able to approve it but I don't think anybody cares about Hurd, so ok.

Likewise.

Do you have access to svn?

I'll try to track down the people and the years (from SVN logs) in which
they contributed, and assemble such a header.


> Do you have access to svn?

No.  No active Hurd person currently has such access.

Here it is, reposted.  It has already been acked by Paolo.  This is what
I'm going to install unless someone objects.

Please also tell me whether this could also be installed on the 4.3 and
4.2 branches.
