Ah, I see why you "think" it works. Here's the output of the log:

As ytou can see, 'support/scripts/apply-patches.sh' uncompresses the
archive because it ends in '.gz', which output a tarball to stdout, and
passes this to 'patch', which ignores whatever it does not recognise,
but eventually find "some" hunks which it applies:

    case "$patch" in
        *.gz)
        type="gzip"; uncomp="gunzip -dc"; ;;
        [--SNIP--]
    esac
    [--SNIP--]
    ${uncomp} "${path}/$patch" | patch -g0 -p1 -E -d "${builddir}"

So, basically, what's hapenning is that a tarball is used as a patch.

If you want my opinion, this is extremely *dirty*. And is in dire need of
be fixed.

You'll excuse me if I refuse to do that on purpose. ;-)

Yann E. MORIN.
