Comment(by joeyadams):

 Here are the problematic lines:

 {{{
 checkBounds "CWchar"     (intRange 32)  (approxBounds random trials
 (undefined:: CWchar))
 checkBounds "CSigAtomic" (intRange 32)  (approxBounds random trials
 (undefined:: CWchar))
 ...
 checkBounds "CWchar R"     (False,-100,100)  (approxBounds (randomR
 (-100,100)) trials (undefined:: CWchar))
 checkBounds "CSigAtomic R" (False,-100,100)  (approxBounds (randomR
 (-100,100)) trials (undefined:: CWchar))
 }}}

 Also, it says `undefined:: CWchar` for both `CWchar` and `CSigAtomic`.  Is
 this a typo?
