-dnl Improved version of AC_CHECK_LIB
-dnl
-dnl Thanks to John Hawkinson ([email protected])
-dnl
-dnl usage:
-dnl
-dnl    AC_LBL_CHECK_LIB(LIBRARY, FUNCTION [, ACTION-IF-FOUND [,
-dnl        ACTION-IF-NOT-FOUND [, OTHER-LIBRARIES]]])
-dnl
-dnl results:
-dnl
-dnl    LIBS
-dnl
-dnl XXX - "AC_LBL_LIBRARY_NET" was redone to use "AC_SEARCH_LIBS"
-dnl rather than "AC_LBL_CHECK_LIB", so this isn't used any more.
-dnl We keep it around for reference purposes in case it's ever
-dnl useful in the future.
