Mageia 2, 32 bit (Linux).

Right, I'll have a look but not soon :-(

I also didn't manage to get gl2ps included in the build (reported earlier);
checking the various related files didn't yield any clues why.
Now, based on your analysis of native-gcc behavior, it occurs to me that I
do not have gl2ps installed on that Mageia system itself, so I'm wondering
if similar mechanisms occur as with native-gcc (i.e., mxe is trying to pull
in gl2ps stuff from the host build system but fails as it isn't there in my
case). A check could be installing gl2ps on Mageia and then rebuilding
mxe-octave with my "old" mxe-octave build chain.

Unfortunately I have very little time until mid-March. Hopefully I'll find a
time slot to do a few Octave things in between.
