Is this still true?

Build parts are ok.

Thanks.

Regarding your question(s)
I believe -fpic/PIC is still broken on Interix but I'll have to dig into 
some old notes to clarify the reason.

The comment about shared library relocation is still true.

Looking at the patch, I didn't spotted anything obviously wrong.

It looks there is no active Interix maintainer listed in MAINTAINERS
file, and since in addition to build parts your patch touches only
Interix specific files, please go ahead and commit the patch to SVN.

So, OK for mainline.

Uros.
