After applying this patch compilation breaks on my box:

  CC       protobuf-desc.o
In file included from protobuf-desc.c:97:0:
protobuf-desc-gen.h: In function ‘cr_pb_init’:
protobuf-desc-gen.h:1:1: error: pasting "PB_" and "/" does not give a valid preprocessing token
protobuf-desc-gen.h:1:1: error: ‘PB_’ undeclared (first use in this function)
protobuf-desc-gen.h:1:1: note: each undeclared identifier is reported only once for each function it appears in
protobuf-desc-gen.h:1:1: error: ‘bin’ undeclared (first use in this function)
protobuf-desc-gen.h:1:1: error: expected expression before ‘/’ token

...

This is because the protobuf-desc-get.h contains

$ head -3 protobuf-desc-gen.h 
CR_PB_DESC(/bin, /bin, /bin);
CR_PB_DESC(/boot, /boot, /boot);
CR_PB_DESC(/cgroup, /cgroup, /cgroup);

instead of

$ head -3 protobuf-desc-gen.h 
CR_PB_DESC(INVENTORY, Inventory, inventory);
CR_PB_DESC(STATS, Stats, stats);
CR_PB_DESC(FDINFO, Fdinfo, fdinfo);
