Hi, thanks for your quick answers!! I found out that compiling with -Werror -Wno-error=missing-field-initializers results in an error, but compiling with -Werror -Wno-missing-field-initializers neither shows the warning nor results in an error! This behaviour differs from the behaviour with other warnings, like unused-parameter or sign-compare. This looks like a bug to me, what do you think? > For a sufficiently recent GCC -fdiagnostics-show-option should show > the option that gives a warning. Thanks, this will help me with a number of other warnings. Markus
