What version of the product are you using? On what operating system?

Windows 7 32bit

Please provide any additional information below.

Succesfully tested patch with mingwbuilds gcc 4.7.2 (mingw-w64), rubenvb gcc 
4.7.2 (mingw-w64), and mingw gcc 4.6.2 (mingw.org).

FYI: I also had to remove the following from my %USERPROFILE%/.hgrc as it 
caused compile failures because it corrupted the content of 
%GOROOT%\VERSION.cache. It caused the first line of the file to be 
"develwarning: failed to set color mode to win32" followed by a second line of 
version info.

  [color]
  mode = win32
