The problem there seems to be that the network library is calling 
functions that do not exist on older versions of Windows.  I don't think 
there's anything that GHC can do about that.

Something C++ specific, by the looks of it.

Are you sure the problem you had isn't just that the C erfc function is 
not available on Windows?

Oh, perhaps the problem that Lennart is referring to is that when GHCi 
loads up a package it requires that all the symbols in the package can 
be resolved, whereas when you statically link a .a library we only have 
to resolve the symbols required by the library modules that the program 
actually refers to.

So one workaround would be to link in a dummy erfc() function, or 
alternatively hack the erf pacakge so that it omits the offending parts 
on Windows.
