Easiest way to find these is to stick -Wall in global CFLAGS (or just |
| 2 |
-Wstrict-aliasing if you want to be more specific), and grep the build |
| 3 |
log for 'will break strict aliasing' (LC_ALL=C obviously). Such |
| 4 |
issues should be filed upstream, I guess, to either get the Makefile to |
| 5 |
forcibly set -fno-strict-aliasing or to rework the code. |

Whether any of these actually trigger real problems or not I don't |
| 54 |
know; but then probaly neither do the upstream developers... |
