Thinking about this a bit - you are probably right that this is due to GCC PR -
i.e. __GI_errno_location being weak/hidden.
However the fix to make it strong, is not a workaround for that PR - but
because
it needs to be strong anyways.
And alternately, the exportable version __errno_location needs to be weak
so that
we don't get redefs when static linking with libpthread etc.
Is this convincing enough to get this v2 patch into trunk :-)
I will push this, thanks.
Thx,
