Bug 1039375

In openSUSE:Factory:Staging:C

https://build.opensuse.org/build/openSUSE:Factory:Staging:C:DVD/standard/x86_64/kbuild/_log

The build is killed by brp for finding implicit function declarations, like for example:

>[  113s] /home/abuild/rpmbuild/BUILD/kbuild-0.1.9998svn2814/src/kObjCache/kObjCache.c: In function 'kObjCacheLock':
>[  113s] /home/abuild/rpmbuild/BUILD/kbuild-0.1.9998svn2814/src/kObjCache/kObjCache.c:4665:9: warning: implicit declaration of function 'flock'; did you mean 'fork'? [-Wimplicit-function-declaration]
>[  113s]      if (flock(pCache->fd, LOCK_EX) != 0)

and then later on

>[  170s] I: Program is using implicit definitions of functions getting
>[  170s]    pointers or implemented by macros. These functions need to use their
>[  170s]    correct prototypes to allow correct argument passing on e.g. x86_64 .

GCC7 is scheduled to become the default compiler and we would really like to get a final push for the missing bits and pieces
