  The latter, certainly.

  I had a quick try in my 4.3.4-4 build dir; it's a simple matter of adding an
extra.def file to the linker flags along with a counterbalancing
'--export-all-symbols' (and since we have a .map file as well this doesn't
over-export, so I don't need to make a complete .def file, handy!) and I could
conditionalize it on any one of the new HAVE_xxx definitions that are what's
causing libgfortan to exclude its own implementations in the new build, so it
doesn't seem like it should be too hard.

  I need to concentrate on fixing LTO for binutils 2.21.1 before I do anything
else.  Apologies to Marco but unless the problem gets worse I'm going back to
that and testing the gcc-4.6.0 RC2 for the next few days.  I'll try and find
some background time in which to respin 4.3.4 with forwarders added to the DLL.

    cheers,
      DaveK
