Gcc3.3, as supplied by cygwin, uses SJLJ. Thus James' octave version
will have this issue.
I have two comments:
- I'm also seeing the compile problems with gcc3.4; however Paul
Soderlind sent me a note that he had no problem with gcc3.4.
Would anyone else like to comment on their experiences with
octave/cygwin/gcc3.4?
- Has anyone tried to compile octave with a gcc version compiled
with --disable-sjlj-exceptions?
