+dnl This is for MinGW, and is used in test/automated/Makefile.in.
+dnl The MSYS Bash has heuristics for replacing ':' with ';' when it
+dnl decides that a command-line argument to be passed to a MinGW program
+dnl is a PATH-style list of directories.  But that heuristics plays it
+dnl safe, and only does the replacement when it is _absolutely_ sure it
+dnl sees a colon-seperated list of file names; e.g. ":." is left alone,
+dnl which breaks in-tree builds.  So we do this manually instead.
+dnl Note that we cannot rely on PATH_SEPARATOR, as that one will always
+dnl be computed as ':' in MSYS Bash.
