Being pedantic here but sourceware.org is just a host
that (I recall) Redhat has provided for years. It is
not a corporate entity or non-profit by itself -- just
a domain for development.
The company who did this is CodeSourcery which is
now part of Mentor Graphics.
In general, my opinion is that they have been
good at upstreaming patches so I would think the
technical part of the patch against the base newlib
they started with is small. With the disclaimer that
sometimes ports like the NIOS II linger in their code
a long time before submitted.
It is a shame that no one from there has commented.
Did they do this to the source for gcc, binutils, etc?
