Sorry, I missed that part.

Yes, because now it is possible to build the development version of 
Octave with support for 64-bit indexing and still use 32-bit indexing in 
the BLAS and other libraries, we need to control the type of index used 
for those libraries separately from whether Octave uses 64-bit indexing. 
 Sorry for the confusion, most likely due to not having a separate 
mxe-octave branch for building stable Octave.  OTOH, I'm not sure we 
really want to add that complexity.

At first I was surprised that Octave was successfully configured with 
--enable-64 when the libraries are using 32-bit indexing, but then I 
remembered that this is a cross build, so we can't run the program that 
is necessary to detect that problem.  So we have to trust that the 
options have been selected correctly.  Sorry.
