Oh yeah, you're right. I forgot that was what it was for.

Yeah, maybe I should do that as well, but I've just started another
build. Re-enabling gnomevfs did NOT work for me - causes segfaults and
wxpython can import the libraries with a "No such process" error after
doing that. Rebuilding now. I guess it could be due to using STL as
well, but we'll see.

That is strange if it's so much faster on your system. Fortunately I
have loads of memory so it's not too much of an issue for me. Most of
the time on 32-bit Cygwin is spent stripping the executables, which is
_way_ slower than on 64-bit Cygwin, by a factor of probably 3-4. Time to
rebuild again anyway. What fun...

Thanks Achim,
