make[2]: *** [obj/pokerth.pb.o] Error 1
Renaming the vars to majorVersion/minorVersion fixes this issue.
The problem on kFreeBSD is, that
/usr/include/sys/kern/types.h
has
#define major(x) ((int)(((u_int)(x) >> 8)&0xff)) /* major number */
#define minor(x) ((int)((x)&0xffff00ff)) /* minor number */
and this is included somewhere when you include stdlib.h, which protobuf's
headers do.
Hurd has similar definitions in /usr/include/i386-gnu/sys/sysmacros.h.
