* sysdeps/posix/writev.c: Likewise. From Momchil Velikov <velco@fadata.bg>. * elf/dl-error.c [! _LIBC_REENTRANT]: Use a static variable instead of calling *GL(dl_error_catch_tsd) for a thread-local location. * elf/rtld.c (startup_error_tsd): Conditionalize on [_LIBC_REENTRANT]. (dl_main): Same for GL(dl_error_catch_tsd) initialization. * elf/dl-tsd.c: Conditionalize contents on [_LIBC_REENTRANT]. * libio/iofflush.c: Add libc_hidden_def. * libio/iofwrite.c: Likewise. * sysdeps/generic/sigtimedwait.c: Likewise. * sysdeps/generic/sigwaitinfo.c: Likewise. * sysdeps/posix/sigwait.c: Likewise. Reported by Momchil Velikov <velco@fadata.bg>. * inet/inet_lnaof.c (inet_lnaof): Change return type to in_addr_t to match <arpa/inet.h> declaration. * inet/inet_netof.c (inet_netof): Likewise. * inet/inet_mkadr.c (inet_makeaddr): Likewise for argument types. Reported by Momchil Velikov <velco@fadata.bg>.
