ghci 6.5 on winxp "panic"/"loadObj: failed"

[Conal Elliott]

I've been able to get "make" and "make install" to complete for building
GHC from CVS HEAD, depositing new compiler etc in /usr/local (under
cygwin).  When I run /usr/local/ghci.exe, I get this error:

bash-2.05b$ /usr/local/bin/ghci
   ___         ___ _
  / _ \ /\  /\/ __(_)
 / /_\// /_/ / /  | |      GHC Interactive, version 6.5, for Haskell 98.
/ /_\\/ __  / /___| |      http://www.haskell.org/ghc/
\____/\/ /_/\____/|_|      Type :? for help.

Loading package base-1.0 ... ghc.exe: panic! (the `impossible' happened,
GHC version 6.5):
	loadObj: failed

Please report it as a compiler bug to glasgow-haskell-bugs at haskell.org,
or http://sourceforge.net/projects/ghc/.


ghc.exe: Unknown PEi386 section name `.ctors'
bash-2.05b$

Does that error message suggest anything?  - Conal
