--- Comment #5 from Robbert van der Helm mail@robbertvanderhelm.nl --- Does there happen to be any documentation on the interaction between that WINE_UNIX_CALL interface and Winelib binaries? My end goal here is not necessarily to create a 32-bit binary or to interact with 32-bit ELF libraries, but I am looking for some solution that lets me load PE32/PE32+ libraries while being able to interact with X11, Unix domain sockets, and some other Linux APIs from a single process. Previously winebuild/winegcc offered a simple and seamless way to get this behavior, with only minor command line argument changes required to get a variant that could load 32-bit PE32 libraries.
