It's interesting, because it was the last argument for me to uninstall Lazarus after experiments with compiling it with different compilers. I read about different OS-es, but the reason was probably different compiler version (or something absolutely different).

Maybe, if you, Micha, submit "patch" to compiler sources (i.e. point the lines you want to be changed) to fpc-devel mail list or something, after a short discussion the developers will add such a hint?

(Of course, only if it is absent in development branch tonow.)
