 I had wondered myself if the problem may actually be octave-octcdf's use
 of -mieee!

I looked into the src/configure file of octave-octcdf.  There is
nothing in it that would add explicitly the -mieee option.  It seems
to appear from mkoctfile -p CPPFLAGS, which does not introduce the
-mieee on my system, but this may be different on alpha.  This is what
I get on my i386 system:

$ grep CPPFLAGS $(which mkoctfile) | grep ^:
: ${CPPFLAGS=-D_FORTIFY_SOURCE=2}

Could anyone do the same on an alpha system?

This is precisely the reason why I want access to an unstable alpha
chroot! According to octave's build log, the mieee option is added to
XTRA_CFLAGS and XTRA_CXXFLAGS, but we need to know whether it ends up in
CPPFLAGS. And asking people, wait for their answer and then ask other
questions simply isn't productive.
