Hello
I have read your reply with a great interest.
I do not know that you have remember it we have discussed the EH on octave.
I do not want to discuss the matter here.
I also have build GCC-4.3.0(gcc, gfortran, g++).
The build by gnuplot4.3 by GCC-4.3.0.
It have been done without problem and the performace of binaries are fairly good compared to those
built by the standard the cygwin GCC.
Of course, it is a fortunate example. In principle, there exist many problems to use it.
I have tried to octave build by GCC-4.3.0, it failed as expected.
For users standpoint, which EH is better sjlj ot dwarf2 does not matter.
Users always would like to seek the fast and stable compliers.
I respect that cygwin team staffs are paying effors for preparing good complilers.
I hope that thier effrots will be successful in the cygwin 1.7.
Sincerely,
Tatsuro MATSUOKA
