Add a configure option '--disable-doc' to disable building of the
documentation by the 'all' target.
Check for the required tools at configure time, and require them if
building documentation is enabled.
Even if building the documentation was diabled with '--disable-doc',
'make -C doc' at the top-level can still make the documentation, if the
documentation tools were found. If the tools were not found, 'missing'
is used to issue a warning about that.
Update instructions for building Cygwin appropriately.
(Building documentation remains the default to increase the chances of
noticing when building the documentation is broken.)

Use AS_HELP_STRING in AC_ARG_WITH for --enable-debugging to ensure
correct formatting in 'configure --help' output.

This avoids warning with autoconf >= 2.70:
configure.ac:47: warning: The macro `AC_CONFIG_HEADER' is obsolete.
AC_CONFIG_HEADERS has been supported since before autconf 2.59, the
minimum version we can be using, controlled by AC_PREREQ.

v2:
* Include tzmap.h in BUILT_SOURCES
* Make per-file flags appear after user-supplied CXXFLAGS, so they can
override optimization level.
* Correct .o files used to define symbols exported by libm.a
* Drop gcrt0.o mistakenly included in libgmon.a
* Add missing line continuations in GMON_FILES value
v3:
* use per-file flags for .c compilation
* override C{XX,}FLAGS, as they are set on the command line by top-level make
v4:
* Drop -Wno-error=write-strings from path_testsuite CXXFLAGS
v5:
* Update for changes in master
- Add -fno-threadsafe-statics to CXX flags
- Add hypotl.cc
- Remove fenv.cc (in favour of newlib), add fenv.c stub
- Add proc.5 manpage rules

There's doesn't seem to be much use in independently distributing these
subdirectories, so allowing them to be independently configured seems
pointless and overcomplicated.
The order in which the subdirectories are built is still a little odd,
as cygwin is linked with libcygserver, and cygserver is then linked with
cygwin. So, we build the cygwin directory first, which invokes a build
of libcygserver in the cygserver directory, and then build in the
cygserver directory to build the cygserver executable.
Drop AC_CONFIGURE_ARGS, since we don't need to recursively call
configure with the same arguments anymore.
Slightly refine when we build utils: Previously we didn't build any
utils if MinGW compiler use was avoided, now we just avoid building
those utils which require that compiler.
Greatly simplify how winsup_srcdir and target_builddir are set, since
we're only configuring from one directory. (These are still kept
absolute, since we don't adjust them where used for being used in a
subdirectory).
Remove configure.cygwin and put it's (greatly reduced) contents inline
in the one place it's used now.
Remove generated configure and aclocal.m4 in subdirectories.

Doing this properly using AC_CONFIG_SUBDIRS is necessary to get the
correct paths in flags given to the compiler specified in CC/CXX.

Remove autoconf variable INSTALL_LICENSE, which has a constant value
which is only used once.

This is only needed if we are using an ancient make which doesn't set
${MAKE}, but we say "This makefile requires GNU make." everywhere.
It only has an effect if @SET_MAKE@ is used, which we aren't doing
consistently.

If S4U proves to be usable alone, remove this code entirely.

Bump GPLv2+ to GPLv3+ for some files, clarify BSD 2-clause.
Everything else stays under GPLv3+.
New Linking Exception exempts resulting executables from LGPLv3 section 4.
Add CONTRIBUTORS file to keep track of licensing.
Remove 'Copyright Red Hat Inc' comments.

Rename without-mingw-progs to with-cross-bootstrap, since it now
disables additional checks that are problematic for cross-compilers.
When cross-compiling a toolchain targeting cygwin, building cygwin1.dll
requires libgcc.
However, building libgcc requires the cygwin headers to be
installed.
Configuring cygwin requries the mingw-crt libraries, which require the
cygwin headers to be installed.
Work around this circular dependency by making the
--with-cross-bootstrap configure option skip cygwin's configure checks
for valid mingw-crt libraries. Cygwin will still properly link against
these libraries if they exist, but this allows configure to succeed even
if the libraries have not been built yet.
Since the mingw-crt libraries only require the cygwin headers to be
installed, this allows us to successfully configure cygwin so that we
can only install the headers without trying to build any
libraries.
