Pedro Alves 91ee7171d0 MinGW and attribute format(printf/gnu_printf)
Cross building gdbserver for --host=x86_64-w64-mingw32 with gcc 4.8.4
20141219 (Fedora MinGW 4.8.4-1.fc20), I get:

  src/gdb/gdbserver/tracepoint.c: In function 'cmd_qtdp':
  src/gdb/gdbserver/tracepoint.c:2577:7: error: unknown conversion type character 'l' in format [-Werror=format=]

     trace_debug ("Making new step traceframe for "
     ^

trace_debug is a macro that calls:

  static void trace_vdebug (const char *, ...) ATTRIBUTE_PRINTF (1, 2);

The calls that fail checking use PRIu64, etc., like:

      trace_debug ("Defined %stracepoint %d at 0x%s, "
		   "enabled %d step %" PRIu64 " pass %" PRIu64,
		   tpoint->type == fast_tracepoint ? "fast "
		   : tpoint->type == static_tracepoint ? "static " : "",
		   tpoint->number, paddress (tpoint->address), tpoint->enabled,
		   tpoint->step_count, tpoint->pass_count);

gnulib's stdio/printf module replacements may make %llu, etc. work on
mingw, instead of the MS-specific %I64u, and thus may make PRIu64
expand to %llu.  However, gcc isn't aware of that, because libiberty's
ansidecl.h defines ATTRIBUTE_PRINTF as using attribute format(printf).
But, with that format, gcc checks for MS-style format strings (%I64u).
In order to have gcc expect gnu/standard formats, we need to use
gnu_printf format instead.  Which version to use (printf/gnu_printf)
depends on msvcrt and mingw version, and so gnulib has a
configure-time check, and defines _GL_ATTRIBUTE_FORMAT_PRINTF
accordingly.

Since _GL_ATTRIBUTE_FORMAT_PRINTF is compatible with ATTRIBUTE_PRINTF,
the fix is simply to make use of the former.

	* common/common-defs.h (ATTRIBUTE_PRINTF): Redefine in terms of

		   README for GNU development tools

This directory contains various GNU compilers, assemblers, linkers, 
debuggers, etc., plus their support routines, definitions, and documentation.

If you are receiving this as part of a GDB release, see the file gdb/README.
If with a binutils release, see binutils/README;  if with a libg++ release,
see libg++/README, etc.  That'll give you info about this
package -- supported targets, how to use it, how to report bugs, etc.

It is now possible to automatically configure and build a variety of
tools with one command.  To build all of the tools contained herein,
run the ``configure'' script here, e.g.:

	./configure 
	make

To install them (by default in /usr/local/bin, /usr/local/lib, etc),
then do:
	make install

(If the configure script can't determine your type of computer, give it
the name as an argument, for instance ``./configure sun4''.  You can
use the script ``config.sub'' to test whether a name is recognized; if
it is, config.sub translates it to a triplet specifying CPU, vendor,
and OS.)

If you have more than one compiler on your system, it is often best to
explicitly set CC in the environment before running configure, and to
also set CC when running make.  For example (assuming sh/bash/ksh):

	CC=gcc ./configure
	make

A similar example using csh:

	setenv CC gcc
	./configure
	make

Much of the code and documentation enclosed is copyright by
the Free Software Foundation, Inc.  See the file COPYING or
COPYING.LIB in the various directories, for a description of the
GNU General Public License terms under which you can copy the files.

REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info
on where and how to report problems.
