I think the right fix for the komp-pid.diff related error is to replace
the Unix/Standard C function calls (that take C strings) to Qt ones, as
there don't seem to be any easy way to convert back TQString to const
char* without messing with locales (TQString is UTF16, const char* is
locale-dependent).
