Is it really possible "gcc-dw2" ?
I think it is grateful for me to build the fast octave if it will be
However, I'm afraid that parallel existence of two different GCCs
confuses the cygwin users.
The best solution, I think, the speed of sjlj-exceptions EH on the
cygwin is as fast as that of other platforms.
The "gcc-dw2" is the second best solution and it should be treated
with great care.
I’m not a specialist on the cygwin and am mere one of the daily
users of the cygwin. I would like to hear the comments and opinions
from the cygwin experts.
Is there any possibility that the speed of sjlj-exceptions EH will be
faster than that of present states?
