You must use GNU `binutils' (as and ld) if you want to build a

shared library. Even if you don't want to build a shared library,

we recommend you use them anyway. No one has tested compilation

with non-GNU `binutils' in a long time.
|

|

The quality of `binutils' releases has varied a bit recently. The
|
||||
bugs are in obscure features, but glibc uses quite a few of those.
|

2.10.1 and later releases are known to work. Versions after

2.8.1.0.23 may or may not work. Older versions definitely don't.
