+
+ * modules/pthread_sigmask (configure.ac): gl_SIGNAL_MODULE_INDICATOR
+ and not gl_SYS_SELECT_MODULE_INDICATOR, fixing a typo exposed
+ in an application that does not use the sys_select module.

+
+ poll: do not return 0 on timeout=-1
+ * lib/poll.c: Loop with yield if no events occured
+
+2011-07-06 Eric Blake <eblake@redhat.com>
+
+ pthread_sigmask: always replace when not using pthread
+ * m4/pthread_sigmask.m4 (gl_PTHREAD_SIGMASK): Force sigprocmask
+ replacement when using some threading other than pthread. Fix
+ logic bug.

+ Comments.
+ * m4/printf.m4: Update comments about mingw.
+
+2011-07-06 Paul Eggert <eggert@cs.ucla.edu>
+
+ sys_select: define sigset_t more portably
+ * lib/sys_select.in.h: Always include <sys/types.h>, since
+ we now need sigset_t and mingw defines it there.
+ Include <signal.h> before split inclusion guard, to avoid
+ mishaps on Solaris, whose <signal.h> eventually includes us.
+ * m4/signal_h.m4 (gl_SIGNAL_H): Require gl_CHECK_TYPE_SIGSET_T.
+ (gl_CHECK_TYPE_SIGSET_T): New macro, most of the contents of
+ which come from ...
+ * m4/signalblocking.m4 (gl_SIGNALBLOCKING): Require
+ gl_CHECK_TYPE_SIGSET_T.
+ (gl_PREREQ_SIGPROCMASK): Now a no-op, since gl_CHECK_TYPE_SIGSET_T
+ does the real work.
+ * modules/sys_select (Depends-on): Add 'signal'.
+
+ * m4/sys_select_h.m4 (gl_HEADER_SYS_SELECT): Poison pselect.
+ Suggested by Bruno Haible.
+
+ pselect: Use pthread_sigmask, not sigprocmask.
+ * lib/pselect.c (pselect): Use pthread_sigmask, as it supports
+ multithreaded apps better than sigprocmask does.
+ * modules/pselect (Depends-on): Depend on pthread_sigmask, not
+ sigprocmask directly.
+
+2011-07-05 Paul Eggert <eggert@cs.ucla.edu>
+
+ * lib/pselect.c (pselect): Use plain name, without "rpl_".
+ Don't #undef, since we don't need any underlying pselect.
+ * modules/pselect (configure.ac): Use our pselect.o if !HAVE_PSELECT.
+ (Depends-on): Add select.
+ (Link): Add $(LIBSOCKET).
+ These changes suggested by Bruno Haible.
+
+ pselect: document better
+ * MODULES.html.sh (Support for systems lacking POSIX:2008): Add it.
+ * doc/posix-functions/pselect.texi (pselect): Document new module.
+
+ pthread_sigmask: new module
+ * MODULES.html.sh (Support for systems lacking POSIX:2008): Add it.
+ * doc/posix-functions/pthread_sigmask.texi: Document new module.
+ * lib/signal.in.h (pthread_sigmask): Arrange for replacement.
+ This is done only as a macro; I don't know how well that'll
+ work for C++. Move <sys/types.h> include before the include_next,
+ to avoid mishap on Solaris.
+ * m4/signal_h.m4 (gl_SIGNAL_H, gl_SIGNAL_H_DEFAULTS): Check for it.
+ * modules/signal (Makefile.am): Substitute the check's results.
+ * modules/pthread_sigmask, m4/pthread_sigmask.m4: New files.
+
+ test-pselect: new module
+ * modules/pselect-tests, tests/test-pselect.c: New files.
+ * tests/test-select.c, tests/test-sys_select-c++.cc:
+ If TEST_PSELECT is defined, test pselect instead of testing select.
+
+ * tests/test-sys_select.c (sigset_t): Test for it, too.
+ Suggested by Bruno Haible.
+
+2011-07-05 Eric Blake <eblake@redhat.com>
+
+ snprintf: guarantee %1$d, for libintl
+ * m4/snprintf.m4 (gl_FUNC_SNPRINTF): Require %1$d support.
+ * m4/vsnprintf.m4 (gl_FUNC_VSNPRINTF): Likewise.
+ * doc/posix-functions/snprintf.texi (snprintf): Update.
+ * doc/posix-functions/vsnprintf.texi (vsnprintf): Likewise.
+ * tests/test-snprintf.c (main): Enhance test.
+ * tests/test-vsnprintf.c (main): Likewise.
+
+2011-07-05 Jim Meyering <meyering@redhat.com>
+
+ maint: exempt stdio-read.c and stdio-write.c from the cppi check
+ * Makefile (sc_cpp_indent_check): Exempt stdio-read.c and stdio-write.c
+ per Bruno's request, to accommodate this idiom (no space after "#")
+ even when the function is inside an #if block:
+ char *
+ gets (char *s)
+ #undef gets
+ {
+ ...
+ }
+
+2011-07-04 Jim Meyering <meyering@redhat.com>
+
+ maint: indent with spaces, not TABs, and add a rule to check this
+ * tests/test-userspec.c: Indent with spaces, not TABs.
+ * tests/test-argp.c: Likewise.
+ * tests/test-c-stack2.sh: Likewise.
+ * tests/test-parse-duration.sh: Likewise
+ * m4/strtod.m4: Likewise.
+ * m4/alloca.m4: Likewise.
+ * m4/pselect.m4: Likewise.
+ * Makefile (sc_prohibit_leading_TABs): Prohibit leading TABs.
+
+2011-07-03 Jim Meyering <meyering@redhat.com>
+
+ maint.mk: correct omissions in prohibit_argmatch_without_use check
+ This rule would mistakenly report that argmatch.h is included without
+ use even when both the argmatch and invalid_arg macro were used.
+ * top/maint.mk (sc_prohibit_argmatch_without_use): Also detect uses
+ of argmatch and invalid_arg.
