I was casting straws by this point.  :)  They seemed logical, and [I'm 
assuming] don't hurt...

I'll throw 2.22 in next pass...

In my case it WAS needed.  gcc was failing configure with

checking for suffix of object files... configure: error: cannot compute
suffix of object files: cannot compile

and one or more of the following fixed that completely. By that point I 
was tired of seeing that particular error :) so just shotgunned them 
all.  I'm sure only one or two of them are needed.
