Can't build on Windows

[Simon Peyton Jones]

It happens with unmodified HEAD too.  Sigh.
Can anyone help?

Gurgah.   GHC is broken on my windows laptop.  See below.  Anyone have any ideas?  Frustrating.
Oddly the symbol is defined in the .exe

bash$ nm inplace/bin/ghc-stage2.exe | grep stg_upd_frame

02c248e0 T _stg_upd_frame_info
This is admittedly on a branch that I have modified; but I have only modified stuff in the front end, nothing in the RTS etc.  I suppose I will try to build a unmodified HEAD too.
can anyone help?  Thanks!
Simon


bash$ c:/code/HEAD/inplace/bin/ghc-stage2 --interactive
