Linaro is maintaining some advanced/more stable/experimental versions
|
|
of newlib, especially for the ARM architecture.
|
|
|
|
Those versions have not been blessed by the newlib comunity (nor have they
|
|
been cursed either!), but they look to be pretty much stable, and even
|
|
more stable than the upstream versions. YMMV...
|
|
|
|
If you do not know what this Linaro stuff is, then simply say 'n' here,
|
|
and rest in peace. OTOH, if you know what you are doing, you will be
|
|
able to use and enjoy :-) the Linaro versions by saying 'y' here.
