GCC4.4 gets confused by anonymous fields + flexible fields, complains:
lib/ofp-actions.h:510: error: flexible array member in otherwise empty
struct
lib/ofp-actions.h:512: error: bit-field ‘build_assert_failed’ width not
an integer constant
lib/ofp-actions.h:514: error: bit-field ‘build_assert_failed’ width not
an integer constant
Fix the problem by specifying the actions length as zero.

Tested manually on RHEL6.6, and via AppVeyor and Travis CI. Everything
seems happy.
