Well, Octave does support the MEX API, so it actually shouldn't be too
hard. I had a quick look at this. To compile the MFITSIO files I had to

  1. Change line 27 in 'Makefile' from

       CC = mex

     to

       CC = mkoctfile --mex

  2. Remove lines that look like this

       #include "matrix.h"

     from 'fits_read_image.c', 'mfitsio.c', 'mfitsio.h',
     'fits_write_image.c', 'fits_read_header.c', 'fits_write_header.c',
     'fits_delete_keyword.c', 'fits_read_image_subset.c' and
     'fits_write_image_subset.c'

Then I was able to successfully compile the files by running 'make'. I
haven't actually tested this as I don't have any images in the proper
format.
