15 There are also two "unofficial" Octave distributions for Cygwin:

19 The binaries here are built using gcc-3.4.4-3 configured with
20 --disable-sjlj-exceptions. Performance is improved by using DWARF
21 exception handling instead of setjump/longjump exception
22 handling. However, to build dynamically loaded .oct files that
23 will work with this version of Octave, you must use the same
24 specially configured version of GCC that was used to build Octave
25 itself and not the version of GCC that is distributed with
26 Cygwin.

33 The binaries here aim to be an officail cygwin distribution of
34 Octave-3.0.x and are built using the version of GCC distributed
35 with Cygwin. Performance of linear algebra functions is fine, but
36 the performance of the scripting language interpreter suffers
37 because of the setjump/longjump exception handling model used in
38 the version of GCC distributed with Cygwin. The advantage is that
39 you don't need a special version of GCC.

43 We hope that Cygwin will eventually have a version of GCC that does
44 not suffer from the performance problem related to setjump/longjump
45 exception handling.
