   1 dnl Provides option to change library probes.

   3 dnl This file provides RRA_ENABLE_REDUCED_DEPENDS, which adds the configure
   4 dnl option --enable-reduced-depends to request that library probes assume
   5 dnl shared libraries are in use and dependencies of libraries should not be
   6 dnl probed.  If this option is given, the shell variable rra_reduced_depends
   7 dnl is set to true; otherwise, it is set to false.

   9 dnl This macro doesn't do much but is defined separately so that other macros
  10 dnl can require it with AC_REQUIRE.
