dnl PAC_SET_HEADER_LIB_PATH(with_option,[default_path])
dnl This macro looks for the --with-xxx=, --with-xxx-include and --with-xxx-lib=
dnl options and sets the library and include paths.
dnl
dnl TODO as written, this macro cannot handle a "with_option" arg that has "-"
dnl characters in it. Use AS_TR_SH (and possibly AS_VAR_* macros) to handle
dnl this case if it ever arises.
