21 | dnl AC_LIB_ARG_WITH is synonymous to AC_ARG_WITH in autoconf-2.13, and | |

23 | dnl require excessive bracketing. | |

28 | dnl AC_LIB_PREFIX adds to the CPPFLAGS and LDFLAGS the flags that are needed | |
29 | dnl to access previously installed libraries. The basic assumption is that | |
30 | dnl a user will want packages to use other packages he previously installed | |
31 | dnl with the same --prefix option. | |
32 | dnl This macro is not needed if only AC_LIB_LINKFLAGS is used to locate | |
33 | dnl libraries, but is otherwise very convenient. | |
