   One interesting thing I've found on GCC-4 is that the callgraph analyzer
   will cross procedure boundaries for all procedures in that particular
   source file.  It can actually detect that error is left uninitialized
   in this situation:
    cc -Wall x.c -c -O2
    x.c: In function 'fubar2':
    x.c:16: warning: 'error' is used uninitialized in this function
    (edit so *valuep is set to 0)

    cc -Wall x.c -c -O2
    (no warning reported)
So you need to go -O2?  -O alone doesn't work?  Maybe we should -O2 
after the release then :)
