No luck with 0x00405AA8, but it could be in libtorrent.dll, which I
will also build with debugging info.  I did manage to find the
following (after loading the cygwin1.dbg symbols):

0x61007038 is in dll_crt0_1(void*)
969     /ext/build/netrel/src/cygwin-1.7.9-1/winsup/cygwin/
No such file or directory.
        in /ext/build/netrel/src/cygwin-1.7.9-1/winsup/cygwin/

However my Cygwin source is in /usr as opposed to /ext/build/netrel,
is there a way to tell gdb to look there instead?

Thank you,
