I cannot build evolution-data-server against glibc-2.11.90-7 in rawhide with an error:
> In file included from camel-lock-client.c:35:

Line 35 of camel-lock-client.c is just #include <sys/wait.h>

It worked fine with glibc-2.11.90-4. I guess I can workaround this by moving sys/wait.h include before stdlib.h include, but I believe it's not the correct fix, as there should be fixed headers instead.
