Define _POSIX_C_SOURCE as 200112L on Solaris.
This is an attempt to suppress some compiler warnings that appeared inthe wake of commit7f798ac: it seems that by default Solaris/illumosdeclares shmdt() to take "char *" not "void *". We'd like the systemheaders to provide modern POSIX APIs, and POSIX 2001 seems to be asmodern as is available there.illumos' standards(7) man page suggests that we might also need todefine __EXTENSIONS__, but let's see what happens with just this.Discussion:https://postgr.es/m/1654508.1733162761@sss.pgh.pa.us
