Is this new gcc supposed to be ABI compatible with 3.2.x? Because I can't link in libraries compiled with an older version of cygwin g++.

I get about 200 of those.
Oh, and my cygcheck took 3.4seconds.
What happens if you use 'fabi-version=1' ? '-fabi-version=0' ?
Also, what does the following command show:
g++ -E -dM - < /dev/null | awk '/GXX_ABI/ {print $3}'
gcc-3.2-3 gives "102"

Ok, it's not really an ABI change. It's just that the newer g++ doesn't provide/require the "___gxx_personality_v0" or "__Unwind_Resume" symbols. So, any library produced with 3.2-3 will not link into an app compiled with 3.3.1-1.
