 I mean the assembly glue, plus stuff required for the usual oddballs 
(pipe(2)?).  The i386 may not be the best template -- too much legacy.  
The Alpha port might be reasonable; or one of the most recent ones.

 I am not sure if GCC 4.2+ can be persuaded to support a non-TLS 
configuration.  And also because I have 4.1 ready and do not necessarily 
want to spend another month or so for porting the 50+ local patches before 
I progress further -- it's not GCC I am trying to work on here!  Various 
distractions have blocked me for long enough -- do you happen to remember 
when I started talking about porting glibc to VAX/Linux?  It must have 
been at least three years now of which two I have had my VAXstation for 
already!

 I'll have a look at the patches from NetBSD people though -- thanks for 
the reference.

 Well, it has to be *designed* properly for a start!  Hopefully during the 
course of implementing a dynamic linker I will get familiar enough with 
the architecture to be competent to discuss a TLS proposal.
