Hey Simon
heres some info about whats happening, and it may point out whats different
http://stackoverflow.com/questions/384502/what-is-the-bit-size-of-long-on-64...
namely: pointers on 64bit windows are 64bit, but c ints are 32bit
hope that helps!

On 32 bit Windows I get this (with HEAD).****
** **
libraries\Win32\Graphics\Win32\GDI\HDC.hs:145:14: Warning:****
Literal 2147483648 of type Int overflows****
** **
The offending code is:****
** **
setTextCharacterExtra dc extra =****
failIf (== 0x80000000) "SetTextCharacterExtra" $****
c_SetTextCharacterExtra dc extra****
** **
The new literal-overflow test objects to 0x80000000 :: Int. I’m not sure if it should object; in this case we are deliberately using the bit-pattern for minBound.****
** **
Also what happens on a 64-bit architecture?****
** **
What should the behaviour here be? ****
** **
- should we use minBound here?****
- what should the new literal-overlflow code do for 0xblah constants?****
** **
This is currently breaking the HEAD build.****
