This patch adds internal hidden definition for mostly of the posix_spawn function so it can be used internally on both popen and system implementations. Checked on x86_64-linux-gnu. * include/spawn.h (__posix_spawn, posix_spawn_file_actions_addclose, __posix_spawn_file_actions_adddup2, __posix_spawn_file_actions_destroy, __posix_spawn_file_actions_init, __posix_spawnattr_init, __posix_spawnattr_destroy, __posix_spawnattr_setflags, __posix_spawnattr_setsigdefault, __posix_spawnattr_setsigmask): New prototype. * posix/spawn.c (__posix_spawn): Add libc_hidden_def. * posix/spawn_faction_addclose.c (__posix_spawn_file_actions_addclose): Add hidden definition. * posix/spawn_faction_adddup2.c (__posix_spawn_file_actions_adddup2): Likewise. * posix/spawn_faction_destroy.c (__posix_spawn_file_actions_destroy): Likewise. * posix/spawn_faction_init.c (__posix_spawn_file_actions_init): Likewise. * posix/spawnattr_destroy.c (__posix_spawnattr_destroy): Likewise. * posix/spawnattr_init.c (__posix_spawnattr_init): Likewise. * posix/spawnattr_setdefault.c (__posix_spawnattr_setsigdefault): Likewise. * posix/spawnattr_setflags.c (__posix_spawnattr_setflags): Likewise. * posix/spawnattr_setsigmask.c (__posix_spawnattr_setsigmask): Likewise.
