As with SysV shared memory, the extension should define its own structure, if struct msgbuf is not found on the system. FreeBSD is a good example for an environment which does not define this structure. glibc only defines it, if all GNU features have been enabled (-D_GNU_SOURCE). In that regard, php_sysvmsg.h needs to stop defining __USE_GNU. An application must not interfere with the C implementation which the sysvmsg extension is doing here clearly. Because __USE_GNU is only a subset of the behavioural changes which are enabled by _GNU_SOURCE, one can expect that it might trigger bugs in the C library or lead to other undesirable results. - Sascha
