Thomas, All,

On 2015-03-07 14:40 +0100, Thomas Petazzoni spake thusly:
> Backported from upstream, will be part of the next release of
> uClibc-ng.

I know this is not the first patch we have against uClibc-ng, but what
will happen when uClibc eventually tags 1.0.0? How will we differentiate
the patch directories between uClibc-1.0.0 and uClibc-ng 1.0.0 ?

(or for any other version, for what it's worth...)

(BTW, there's no bc8a6a6 commit upstream, it's b15663c)

Yann E. MORIN.
