-#
-# This library contains modules only available in versions of GHC
-# newer than the current one. They are implemented as stubs that
-# #include the actual code from fptools/libraries.
-#
-# The idea is to ease the task of writing portable code in GHC and its
-# tools: the client can link with libghccompat.a and assume that all
-# the modules are available. In this way we can add modules to the library
-# and start using them right away in GHC, as long as the new library modules
-# can be compiled using older versions of GHC.
