As far as I can tell from revision history, there's no good reason to call these files .so instead of .dll in Windows, so use the normal extension. Also change PipSquak from SHARED to MODULE -- it's never passed to target_link_libraries() and only loaded via dlopen(), so MODULE is more appropriate. This makes it possible to delete a workaround for SHARED ldflags being not quite right as well. No intended behavior change. https://reviews.llvm.org/D46898 llvm-svn: 332487
