This adds a test to ensure that the problems fixed in the last several patches do not recur. Each directory checks the headers that it installs for two properties: first, each header must be compilable in isolation, as both C and C++, under a representative combination of language and library conformance levels; second, there is a blacklist of identifiers that may not appear in any installed header, currently consisting of the legacy BSD typedefs. (There is an exemption for the headers that define those typedefs, and for the RPC headers. It may be necessary to make this more sophisticated if we add more stuff to the blacklist in the future.) In order for this test to work correctly, every wrapper header that actually defines something must guard those definitions with #ifndef _ISOMAC. This is the existing mechanism used by the conform/ tests to tell wrapper headers not to define anything that the public header wouldn't, and not to use anything from libc-symbols.h. conform/ only cares for headers that we need to check for standards conformance, whereas this test applies to *every* header. (Headers in include/ that are either installed directly, or are internal-use-only and do *not* correspond to any installed header, are not affected.) * scripts/check-installed-headers.sh: New script. * Rules: In each directory that defines header files to be installed, run check-installed-headers.sh on them as a special test. * Makefile: Likewise for the headers installed at top level. * include/aliases.h, include/alloca.h, include/argz.h * include/arpa/nameser.h, include/arpa/nameser_compat.h * include/elf.h, include/envz.h, include/err.h * include/execinfo.h, include/fpu_control.h, include/getopt.h * include/gshadow.h, include/ifaddrs.h, include/libintl.h * include/link.h, include/malloc.h, include/mcheck.h * include/mntent.h, include/netinet/ether.h * include/nss.h, include/obstack.h, include/printf.h * include/pty.h, include/resolv.h, include/rpc/auth.h * include/rpc/auth_des.h, include/rpc/auth_unix.h * include/rpc/clnt.h, include/rpc/des_crypt.h * include/rpc/key_prot.h, include/rpc/netdb.h * include/rpc/pmap_clnt.h, include/rpc/pmap_prot.h * include/rpc/pmap_rmt.h, include/rpc/rpc.h * include/rpc/rpc_msg.h, include/rpc/svc.h * include/rpc/svc_auth.h, include/rpc/xdr.h * include/rpcsvc/nis_callback.h, include/rpcsvc/nislib.h * include/rpcsvc/yp.h, include/rpcsvc/ypclnt.h * include/rpcsvc/ypupd.h, include/shadow.h * include/stdio_ext.h, include/sys/epoll.h * include/sys/file.h, include/sys/gmon.h, include/sys/ioctl.h * include/sys/prctl.h, include/sys/profil.h * include/sys/statfs.h, include/sys/sysctl.h * include/sys/sysinfo.h, include/ttyent.h, include/utmp.h * sysdeps/arm/nacl/include/bits/setjmp.h * sysdeps/mips/include/sys/asm.h * sysdeps/unix/sysv/linux/include/sys/sysinfo.h * sysdeps/unix/sysv/linux/include/sys/timex.h * sysdeps/x86/fpu/include/bits/fenv.h: Add #ifndef _ISOMAC guard around internal declarations.
