GHC runtime linker: fatal error: I found a duplicate definition for symbol
I found GHC panic when using both inline-c and local Win32 package.
I don't know whether it's related to #6107.

GHC runtime linker: fatal error: I found a duplicate definition for symbol

whilst processing object file
D:\ghc-bug-maybe\.stack-work\install\0464eb7a\lib\x86_64-windows-ghc-7.10.3\Win32a-2.3.1.0-JATTCAFziPX9UILXdwDTPA\HSWin32a-2.3.1.0-JATTCAFziPX9UILXdwDTPA.o
This could be caused by:
* Loading two different object files which export the same symbol
* Specifying the same object file twice on the GHCi command line
* An incorrect `package.conf' entry, causing some object to be
loaded twice.
ghc.exe: panic! (the 'impossible' happened)
(GHC version 7.10.3 for x86_64-unknown-mingw32):
