Do I need to --force these? See below.

| You don't need to do this.I got this from the Cygwin FAQ, regarding [EMAIL PROTECTED] errors. When I didn't do this, after autoconf and libtoolize, I still get:

$ cygcheck -c autoconf-devel automake-devel libtool-devel Cygwin Package Information Package Version Status autoconf-devel 2.59-1 OK automake-devel 1.7.9-1 OK libtool-devel 1.5-3 OK
FWIW, I tried rebuilding clamav (which has a libclamav) by just adding - -no-undefined and the main() function, and both the dll and all executables dependent on it are built, but when I try running those programs they segfault with a STATUS_ACCESS_VIOLATION. When I automake/libtoolize without adding a main(), I get:

This whole thing of making DLLs is something that I would REALLY like to get figured out. Thanks!
