 Replying to [comment:18 igloo]:
 > I don't think it's worth working around this in GHC

 I think this is not a workaround as the linker flags should not indeed
 passed when no linking is done.  I do not think that the warning is bogus.
 It is just a more fine-grained way to pass the flags only when they are
 really needed.


 > (a) it doesn't cause any real problems, just prints some warnings

 ...for every Haskell module, which -- as I wrote above -- triples the
 number of the messages printed to the screen.  I do not think that it is
 good to see such messages all the time.


 > (b) it can be solved by upgrading to a recent gcc.

 It is not by accident that the FreeBSD base system does not have a more
 recent GCC, folks here are moving to a Clang/LLVM instead.  Of course, I
 could use a newer GCC by adding it as a dependency for the port, but I was
 trying to avoid this.

 Anyways, since GCC is going to be removed from the base system in the next
 major release, I shall switch to this solution soon... :-)


 > I have just pushed a patch to fix the problem that `LdCmd` wasn't
 getting defined in the bindist `configure.ac`, though. Thanks for spotting
 that.

 Great, thanks!
