commit ba02fef995ac3fef5c67260015c2ef754943643a Author: Corinna Vinschen <[email protected]> Date: Wed Feb 2 21:16:35 2022 +0100 Cygwin: Makefile.am: fix DLL build rule A single Makefile rule creates three files in three steps, the second and third one never showing up in dependencies. The next step creating the link lib only depends on the first of these files. Even if the second or third step in the DLL build rule fails, the next make invocation never picks up on this and just goes ahead creating the link lib. Fix this by splitting the DLL build rule into three rules, with every step on the way depending on the previous rule. Also fix up the names, TEST_DLL_NAME just doesn't cut it.
