Compiler invocation for generated GUI Component

The following compile messages are printed while trying to build DVBCUT
obtained from https://github.com/nextghost/dvbcut-qt4 on FreeBSD 11-CURRENT
with the llvm-3.3 based Clang as included as base compiler in that version.

Compilation succeeds with -O0, but fails with -O1 or higher.

A similar problem is reported for moc_progresswindow.cpp. I attach the
diagnostic files from that compilation, too.

--- moc_progressstatusbar.o ---
Global is external, but doesn't have external or dllimport or weak linkage!
void (%class.progressstatusbar*, i8*, ...)*
@_ZThn16_N17progressstatusbar5printEPKcz
invalid linkage type for function declaration
void (%class.progressstatusbar*, i8*, ...)*
@_ZThn16_N17progressstatusbar5printEPKcz
Broken module found, compilation aborted!
