I'm running 32 bit Cygwin on a 64 bit machine to build 32 bit binaries. Trying
to build a simple program fails due to a pathing issue related to g++/cc1plus.
I've tried several Cygwin re-installs, so that is not the issue. Calling "g++
foo.cpp" just hangs and never terminates. The program is a simple: int
main(){return 0;}.
I get the following from strace. This shows that the initialization path is
\??\C:\Windows instead of \??\C:\cygwin. I don't know where this is coming
from.
0 0 [main] cc1plus (9284)

At the end of the output, I see this, which is a problem because it's a
blocking read to a path that doesn't exist.

Thanks so much for your help!
