There are only 2 places where wine prints that error message

file dlls/dbghelp/dwarf.c

lines     
 486         FIXME("Unhandled attribute form %lx\n", abbrev_attr->form);
 596         FIXME("Unhandled attribute form %lx\n", abbrev_attr->form);

I looked into the source code and it's unclear what actually is needed to add
or how to confirm that its actually already fixed.
