Almost certainly, there is something wrong in your code, or in the way 
you have declared your external data - the "-Wuninitialized" flag should 
not give false positives as you describe.  (It can give false positives, 
when you know yourself that all code paths that use the data have 
initialised the variables but the compiler is unable to prove this.)
