11 | dnl AC_LIB_ARG_WITH is synonymous to AC_ARG_WITH in autoconf-2.13, and |
12 | dnl similar to AC_ARG_WITH in autoconf 2.52...2.57 except that is doesn't |
13 | dnl require excessive bracketing. |

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