Patches to compile SAOimage-13.5.1 under a 64-bit openSUSE
environment are available in www.mpia.de/~mathar/progs/saoimage-1.35.1.patch .
After using the 2008 FC patches that move around a lot
of local static function declarations, the thing does compile
but crashes with some images. This can be traced back to a problem of integer
declarations when reading FITS images with the BITPIX=32 setting
(patched with a -D in a makefile), plus the necessity to understand
the difference between NULL and 0 at some places.
