Comment (by ballapete):

 The two patches `jukivili (Jussi Kivilinna)` supplied worked – I only had
 to translate them into `unified diff output format` (and made one mistake
 which I had to find). I asked Jussi whether I may publish them here. The
 simpler one removes `#pragma`s from incorrect places, which newer
 compilers might accept. The other set of patches solves the problem of
 repeated `typedef`s.
