Missing 'ErrorHdrHook' in GHC 6.0

[Kevin S. Millikin]

I just switched to GHC 6.0 for a project where I have "plugins" that 
are written in Haskell and reside in a Win32 DLL.

I can make everything work with 6.0, except I get this when building 
the DLL:

d:/ghc/ghc-6.0/libHSbase.a(TopHandler__7.o)(.text+0xc8):ghc7504.hc: 
undefined reference to `ErrorHdrHook'
dllwrap: gcc exited with status 1

I wonder why it's just ErrorHdrHook that can't be found?  My solution 
is to include this:

void ErrorHdrHook(FILE *where) {
    fprintf(where, "\n");
}

in the DLL.
