 - Macro: AC_CHECK_LIB (LIBRARY, FUNCTION [, ACTION-IF-FOUND [,
          ACTION-IF-NOT-FOUND [, OTHER-LIBRARIES]]])
     Try to ensure that C function FUNCTION is available by checking
     whether a test C program can be linked with the library LIBRARY to
     get the function.  LIBRARY is the base name of the library; e.g.,
     to check for `-lmp', use `mp' as the LIBRARY argument.

     ACTION-IF-FOUND is a list of shell commands to run if the link
     with the library succeeds; ACTION-IF-NOT-FOUND is a list of shell
     commands to run if the link fails.  If ACTION-IF-FOUND and
     ACTION-IF-NOT-FOUND are not specified, the default action is to
     add `-lLIBRARY' to `LIBS' and define `HAVE_LIBLIBRARY' (in all
     capitals).

AC_CHECK_LIB(crypt, crypt, [LIBS="$LIBS -lcrypt"]) should do it
