PR ld/12742
* configure.in (AC_CHECK_HEADERS): Test for windows.h and dlfcn.h. * plugin.c: Guard include of dlfcn.h if HAVE_DLFCN_H is defined. Add windows.h header include if HAVE_WINDOWS_H is defined. (dlerror): New static function if windows variant is used instead of dlfcn.h. (dlclose): Likewise. (dlopen): Likewise. (dlsym): Likewise. * configure: Regenerated. * config.in: Regenerated.
