#3536: ghci doesn't resolve libm symbols properly on Windows

---------------------+------------------------------------------------------
The erf package on hackage uses the libm functions erf and erfc.
This all works fine in ghc, but in ghci we get an error.
To repeat:
{{{
cabal install erf
}}}
Try compiling
{{{
import Data.Number.Erf
main = print $ erf (1::Double)
}}}
and it works fine.
Now try
{{{
ghci
:m +Data.Number.Erf
print $ erf (1::Double)
}}}
and the result is
{{{

Loading package base-3.0.3.1 ... linking ... done.
