I have met the phenomena when tried octave 4.2.1 for windows with 64 index.
At first I built without --enable-fortran-int64.
That gave many errors for __run_test_suite__ and could not be used practically.

See jwe's statements in the thread.

The difference between stable and default in the mxe octave is in the internal 
code of octave.
we could not find any differences in configure checks.

I perhaps forgot to add --enable-devel-tools for mxe-octave.
I will check that and if I had make mistake, i rebuild and re-uploade 
corrected binary.

I do not know.
I added address jwe (chief developper) and John D (the most working person on 
mxe octave)
 to the send list of the mail.

I hope that they will answer to your quesstion.
