Re: How to build a Linux newlib?

[Jeff Johnston <jjohnstn at redhat dot com>]

Try updating and rebuilding.  I had some fixes that weren't checked in 
for just such a problem.  The linux build uses a combination of newlib 
and system headers and it is prone to breakage when glibc changes.  In 
this case, stddef.h was no longer being brought in automatically from a 
glibc header.
