Linux: Use in-tree copy of SO_ constants for !__USE_MISC [BZ #24532] The kernel changes for a 64-bit time_t on 32-bit architectures resulted in <asm/socket.h> indirectly including <linux/posix_types.h>. The latter is not namespace-clean for the POSIX version of <sys/socket.h>. This issue has persisted across several Linux releases, so this commit creates our own copy of the SO_* definitions for !__USE_MISC mode. The new test socket/tst-socket-consts ensures that the copy is consistent with the kernel definitions (which vary across architectures). The test is tricky to get right because CPPFLAGS includes include/libc-symbols.h, which in turn defines _GNU_SOURCE unconditionally. Tested with build-many-glibcs.py. I verified that a discrepancy in the definitions actually results in a failure of the socket/tst-socket-consts test. 2019-07-24 08:59:34 +00:00			`/* Socket constants which vary among Linux architectures.
