problem building gccgo on Fedora 10

[Chris Card]

I'm trying to build gccgo on Fedora 10.
First I hit the issue with <linux/user.h> which I replaced by <sys/
user.h> in mksysinfo.sh, but now I'm getting these errors:

Any ideas?

I hope to fix this soon, but in the meantime see this patch from
Martin Capitanio may help.

Thanks Ian,
I'll give that a try

... and it worked. Thanks again

Please forgive my ignorance, but what exactly, should I do do apply
this patch? I'm trying to build gccgo on my Ubuntu 9.10 machine.

Thanks a lot

The 'patch' command will apply patches. See `man patch`.

You no longer need to apply that patch, I have committed a different
fix to the gccgo branch.
