commit 8a31aa37bc97215f137fc705b5f6e43e06683c15 Author: Corinna Vinschen <cori...@vinschen.de> Date: Wed Jun 1 13:12:08 2016 +0200 dlopen: Add dot to filename if no slash is present We're appending a dot to the filename before calling LoadLibrary to override ".dll" automagic. This only worked for paths, not for simple filenames since it required a slash in the pathname. Fix that.
