This was caused by insufficient alignment of Double-typed temp
variables, fixed in r23146.
Moreover, it appeared that function UnixToWinAge wasn't doing anything
useful since year 2005, so it was removed in r23145, making
FindFirst/FindNext routines somewhat faster (and able to run without FPU).
Now I am able to run the big-endian MIPS compiler on QEMU. Hoping you'll
be able to reproduce it, too.
I'll see what I can do, but I've not got any real hardware running here
which is causing me problems (Qemu performance isn't brilliant).
