Interesting and annoying, too:
I have tried: -arch=i386 -arch=x86_32 arch=i386 arch=x86_32
Even:
<key>arch</key>
<string>x86_32</string>
and
<key>arch</key>
<string>i386</string>
So what now?
I am still in 64bit mode.
Otherwise it works for me very good, but I really miss ParagonNTFS.
(and ntfs3g is too slow, tuxera is expensive)
