building ghc-6.8.2 network library fails under gcc43

[Jens Petersen]

(I know gcc-4.3 is still under development, but it is expected to be
the version of gcc in Fedora 9 which will be released around the end
of April.)

Has anyone tried or managed to build ghc with gcc-4.3?  I tried
yesterday in the Fedora buildsystem and got to:

Before investigating further I just wondered if anyone has already
looked at this and might have a patch or workaround?
