Miscellaneous fixes to validate on PPC Mac OS X
The attached patches, (in-?)conveniently separated by affected file, fix the following warnings that have prevented a successful validate on PPC Mac OS X recently:
/Users/thorkilnaur/tn/install/ghc-6.6-for-buildbot-20070221_1000/bin/ghc -Werror -H64m -Onot -fasm -istage1/utils -istage1/basicTypes -istage1/types -istage1/hsSyn -istage1/prelude -istage1/rename -istage1/typecheck -istage1/deSugar -istage1/coreSyn -istage1/vectorise -istage1/specialise -istage1/simplCore -istage1/stranal -istage1/stgSyn -istage1/simplStg -istage1/codeGen -istage1/main -istage1/profiling -istage1/parser -istage1/cprAnalysis -istage1/ndpFlatten -istage1/iface -istage1/cmm -istage1/nativeGen -Wall -fno-warn-name-shadowing -fno-warn-orphans -Istage1 -cpp -fglasgow-exts -fno-generics -Rghc-timing -I. -Iparser -package unix -ignore-package lang -recomp -Rghc-timing -O -fasm -H16M '-#include "cutils.h"' -DUSING_COMPAT -i../compat -ignore-package Cabal -c nativeGen/RegCoalesce.hs -o stage1/nativeGen/RegCoalesce.o -ohi stage1/nativeGen/RegCoalesce.hi
nativeGen/RegAllocLinear.hs:161:11:

nativeGen/RegAllocLinear.hs:161:15:

Fixing this leads to:

nativeGen/RegAllocLinear.hs:157:0:
Warning: Pattern match(es) are non-exhaustive
In the definition of `getFreeRegs':

Then there is:

All warnings being fixed by patches to the respective files.
Thanks to Ben Lippmeier and Ian Lynagh for their generous help.
