 I think you might be not be taking into account the fact that
-Wno-uninitialized _suppresses_ the warnings about uninitialized variables
which are enabled by -Wuninitialized or by -Wall (used by wx). So the above
does explain it: wx build does not use -Wno-uninitialized and hence
generates the warnings while LMI build suppresses the warning with
-Wno-uninitialized and so no warnings are output.

 Am I missing something?
