The following type of warning errors...

  ../../../source/tools/acpibin/abcompare.c: In function 'AbCompareAmlFiles':

  ../../../source/tools/acpibin/abcompare.c:462:5: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing]

       if (*((UINT32 *) Header1.Signature) != *((UINT32 *) Header2.Signature))

results from '-fstrict-aliasing', which is turned on by the specifying of

the '-O2' optimization option. The solution is to turn it off by specifying

'-fno-strict-aliasing'. At least, this appears to be a better solution

than leaving it turned on but disabling the warnings by specifying

'-Wstrict-aliasing=0'.
