There's one other gotcha to bear in mind when using external libraries: if the library contains a ``main()`` function, then this - will be linked in preference to GHC's own ``main()`` function (eg. - ``libf2c`` and ``libl`` have their own ``main()``\ s). This is - because GHC's ``main()`` comes from the ``HSrts`` library, which is - normally included *after* all the other libraries on the linker's - command line.
