Well, yes, there are two tests in configure, but only a single macro in
lftp.m4. AC_TRY_RUN compiles the first argument and then tries to run it
(if not cross-compiling). The second argument is executed if the run
succeeds, the third argument if the compilation or the run fails, the
fourth argument if compilation succeeds but it cannot be ran because
There are a number of other instances of AC_TRY_RUN in the lftp
configure scripts, but the others all have the fourth argument.
