Re: Packaging native newlib

[Jeff Johnston <jjohnstn at redhat dot com>]

Platforms have the ability to override headers with machine-specific versions. 
Ther are also shared headers in the libc/include directory.  Obviously, 
machine-specific headers are not portable.  You say native newlib.  Well, newlib 
is only native in a few rare cases.  Cygwin for example, and linux as anothe 
example.  Linux currently is only supported for x86.  If it was supported for 
another platform, say, arm-linux, then there would be machine-specific versions 
of some of the headers in libc/sys/linux/machine/xxxx.  Look at the 
install-data-local target in Makefile.am.
