Now the bootstrap stops later on with:

Probably improper patch to make it build somehow.

With this patch libgomp builds again for me. This patch is most likely not
accurate, so please fix proper.

In gomp_iter_dynamic_next() and gomp_iter_guided_next() i added a check for an
early return, which is of course not needed to fix the bootstrap failure.

Better mv ansidecl.h to libgomp.h per rth on IRC.

How are you configuring?  I can't reproduce *any* of these failures.

Ah, so it falls into the category of Your Own Fault.  Remove those bogus
extra warning flags and you won't have this problem.
