NMAKE : fatal error U1077: ‘sed’ : return code ‘0x1’

When trying to build Wireshark I get NMAKE : fatal error U1077: 'sed' : return code '0x1'

Or to be more precise I get :

c:\wireshark>nmake -f Makefile.nmake all

When running verifying tools I get:

I've reinstalled sed with Cygwin and it hasn't helped. I've tried the solution from http://ask.wireshark.org/questions/7991/nmake-fatal-error-u1077-sed-return-code-0x1 and no difference.

Now I don't know what to try, any tips?
