Subject: [iproute PATCH v3 0/6] Big C99 style initializer rework

This is v3 of my C99-style initializer related patch series. The changes
since v2 are:

- Flattened embedded struct's initializers:
  Since the field names are very short, I figured it makes more sense to
  keep indenting low. Also, the same style is already used in
  ip/xfrm_policy.c so take that as an example.

- Moved leftover nlmsg_seq initializing into the common place as well:
  I was unsure whether this is a good idea at first (due to the
  increment), but again it's done in ip/xfrm_policy.c as well so should
  be fine.

- Added a comma after the last field initializer as suggested by Jakub.

- Dropped patch 7 since it was NACKed.

- Eliminated checkpatch non-compliance.

- Second go at union bpf_attr in tc/tc_bpf.c:
  I figured that while it is not possible to initialize fields, gcc-3.4.6
  does not complain when setting the whole union to zero using '= {0}'.
  So I did this and thereby at least got rid of the memset calls.

For reference, here's the v2 changelog:

- Rebased onto current upstream master:
  My own commit a0a73b298a579 ("tc: m_action: Use C99 style initializers
  for struct req") contains most of the changes to tc/m_action.c already,
  so I put the remaining ones into a dedicated patch (the first one here)
  with a better description.

- Tested against gcc-3.4.6:
  This is the oldest gcc version I was able to install locally. It indeed
  does not like the former changes in tc/tc_bpf.c, so I reverted them.
  Apart from emitting many warnings, it successfully compiles the
  sources.

In the process of compatibility testing, I made a few more changes which
make sense to have:

- New patch 5 allows to conveniently override the compiler via command
  line.

- New patch 6 eliminates a warning with old gcc but looks valid in
  general.

- A warning made me look at ip/tcp_metrics.c and I found a minor code
  simplification (patch 7).

Phil Sutter (6):
  tc: m_action: Improve conversion to C99 style initializers
  Use C99 style initializers everywhere
  Replace malloc && memset by calloc
  No need to initialize rtattr fields before parsing
  Makefile: Allow to override CC
  misc/ifstat: simplify unsigned value comparison
