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 sees a colon-separated 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.
