I updated and rebuilt with clang-devel (7.0)
Finally, this compiler completes build! I install but things do not work 
better.

I rerun configure of gnustep-base and notice that the obj-c availability 
test fails with this error:


| int main(int argc, char **argv) {
| pid_t t = syscall(SYS_gettid); return t == -1 ? 1 : 0; }

configure: failed program was:

This hints that libobjc.so is not properly linked or misses atomic_load 
for some reason.
