Hello everybody

                Has anyone out there any idea what causes the following
error from the "cplus.exe" program in the demo files (the "demo" directory
is part of the b14 release for those who are looking for it, IMHO it's worth
getting). "cplus.exe" succesfully demonstrated exception handling in in b14
but hasn't worked since and still doesn't work with b17. Using the
libstdc++.a from b14 didn't solve this problem in b16 and doesn't in b17.
I'm running W95 on a Pentium.

(cplus.exe 1099) In cygwin_except_handler

I don't know what the 1099 represents in the above output but it goes up by
1 for each command entered in bash between attempts to execute cplus.exe ?

In passing we still have "Complex.h" and "complex.h" in /include/g++

Other than that, thanks to cygnus for b17, getting better all the time.
