+# By default when MSYS2 executable (bash.exe in particular) runs another

+# http://www.mingw.org/wiki/Posix_path_conversion
+#
+# So when you run b /v=X, build2 gets 'C:/msys64/v=X' argument instead of

+# variable, so all arguments starting with / will not be converted. You can
+# list more prefixes using ';' as a separator.
