DWARF 2 or 4?

[Christopher Meng]

Hi,

One of my package generates debuginfo by specifying -gdwarf-2 option
in CFLAGS. As gcc 4.8 onwards DWARF4 is the default, is it still
acceptable to use this option for Fedora now? Since DWARF4 provides
many features demonstrated at [1], Should I remove that option?

Thanks.
