Yaakov Selkowitz 79e419de62 Rework handling of basename variants
As a commonly-included header, the #define basename in <string.h> can
affect code which uses "basename" for its own purposes (e.g. struct
members or C++ namespaced functions).  When such cases occur and some
code includes <string.h> and some not, then errors result.  OTOH,
<libgen.h> is rarely used, and that's where the renaming occurs in
glibc, so code using <libgen.h> should already be safe.

* libc/include/libgen.h (basename): Define as __xpg_basename
for source compatibility with glibc.
Declare with __ASMNAME("basename") for ABI compatibility.
* libc/include/string.h (basename): Define as basename for
source compatibility with glibc.
Declare with __ASMNAME("__gnu_basename") for ABI compatibility.

Corinna Vinschen f9b87aaf10 Fix sys/time.h build problem due to inconsistent macro usage
https://sourceware.org/ml/newlib/2015/msg00520.html describes
	how sys/time.h uses __BSD_VISIBLE while the types used in the
	affected inline functions are guarded with !_POSIX_SOURCE.
	Fix that by guarding the type with __BSD_VISIBLE as well.

        * libc/include/sys/time.h: Explicitely include sys/cdefs.h.
        * libc/include/sys/types.h: Ditto.  Guard BSD convenience base types
        with __BSD_VISIBLE rather than !_POSIX_SOURCE.

Sebastian Huber 757c0871f7 Prevent use of uninitialized file lock
The CHECK_INIT() is necessary before the _newlib_flockfile_start() since
this would use otherwise acquire an uninitialized lock which gets
initialized after this leading to a corrupt release.

newlib/ChangeLog
2015-07-01  Sebastian Huber  <sebastian.huber@embedded-brains.de>

	libc/stdio/fputs.c (_puts_r): Add missing CHECK_INIT().
	libc/stdio/gets.c (_gets_r): Add missing _REENT_SMALL_CHECK_INIT() and
	CHECK_INIT().  Use _stdin_r() to get the file pointer instead of stdin.

Jon TURNEY 153385d847 Use source files which have makedoc markup, but aren't processed or included.
These source files have makedoc markup, but aren't listed to be chewed by
makedoc. I am assuming that is accidental.

Future work: Note that stdio/fseeko.c, stdio/ftello.c and common/s_isnand.c have

If the newlib .info files are installed using install-info, 'info libc' and
'info libm' don't work.

This seems to be due to the formatting of the directory entry line not being
quite right, so fix that.

Also use @direntry texinfo command, rather than writing .info directory entry
literally.

Also use @dircategory texinfo command to place into 'Newlib' category, rather
than ending up in 'Miscellaneous'
