[Haskell-cafe] When is extra-libraries config in .cabal

[Edward Ing]

Before solving the problem, GHC builds would proceed fine. The link
problem occurred during runtime.

What libraries on the Windows operating would the build have succeeded
on? Win32 Api -- do those have the standard C functions.

If these libraries are available, I wonder why the link failed during runtime.

(There is a libmsvcrt.a under  c:\ghc\ghc-6.6.1\gcc-lib, should this
have played a role? )
