ASSERT when cross compiling to QNX with Debug enabled

[Nathan Hüsken]

I found something out :).

When editing libraries/base/GHC/Int.hs

and change:

instance Bounded Int32 where
    minBound = -0x80000000
    maxBound =  0x7FFFFFFF

to

instance Bounded Int32 where
    minBound = -0x7FFFFFFF
    maxBound =  0x7FFFFFFF

the Assert disappears.
This is of course no solution!
But I thought I should share.
