| dnl which contains the path of the in-tree pkgconfig directory first |
| dnl and then any paths specified in PKG_CONFIG_PATH. |

| dnl We do this mostly so we don't have to use unportable shell constructs |
| dnl such as ${PKG_CONFIG_PATH:+:$PKG_CONFIG_PATH} in Makefile.am to handle |
| dnl the case where the environment variable is not set, but also in order |
| dnl to avoid a trailing ':' in the PKG_CONFIG_PATH which apparently causes |
| dnl problems with pkg-config on windows with msys/mingw. |
