RTS warnings

[Gabor Greif]

Hi all!

I spottes these warnings in today's

   $ make INTEGER_LIBRARY=integer-simple V=0

build:

rts/Stats.c: In function 'stat_exit':

rts/Stats.c:695:0:
     warning: format '%16zu' expects type 'size_t', but argument 2 has
type 'unsigned int'

rts/sm/Storage.c: In function 'flushExec':

rts/sm/Storage.c:1294:0:
     warning: implicit declaration of function '__builtin___clear_cache'

rts/sm/Storage.c:1294:0:
     warning: nested extern declaration of '__builtin___clear_cache'


this is my "GCC":

ggreif$ gcc --version

PS: there is also this low-hanging fruit:

libraries/containers/Data/IntSet/Base.hs:1196:17: Warning:
    In the use of 'bitSize' (imported from Data.Bits):
    Deprecated: "Use bitSizeMaybe or finiteBitSize instead"
