When using a compiler that automatically enables -D_FORTIFY_SOURCE,
building winsup fails with errors like below. Since winsup is not
setup to compile itself with _FORTIFY_SOURCE, disable it for now.

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.
ccwrap massages the compiler's standard include directories to remove
'/usr/include/w32api', with the intent of allowing it to be overriden by
'--with-windows-headers' (See 4c36016b).
I'm not 100% convinced that this is always working as desired, since in
some places w32api includes are done using <w32api/something.h>, which
will find them via the path /usr/include.
If this does turn out to be needed, this could also be implemented by
constructing the appropriate compiler flags once, rather than on every
compiler invocation.

looping.
2012-11-22 Christopher Faylor <me.cygwin2012@cgf.cx>
* Makefile.in: Revamp for new configury.
(datarootdir): Add variable setting.
(winver_stamp): Accommodate changes to mkvers.sh setting.
(libc.a): Fix race when libm.a might not have been built yet.
* configure.in: Revamp for new configury.
* aclocal.m4: Regenerate.
* configure: Ditto.
* autogen.sh: New script.
* mkvers.sh: Find include directives via CFLAGS and friends rather than
assuming that w32api lives nearby.
utils/ChangeLog:
2012-11-12 Christopher Faylor <me.cygwin2012@cgf.cx>
* aclocal.m4: Regenerate.
* configure: Ditto.
* autogen.sh: New script.
* configure.in: Revamp for new configury.
* Makefile.in: Revamp for new configury. Rename ALL_* to just *.
Always use "VERBOSE" setting.
(MINGW_CXX): Don't include CFLAGS in definition.
(all): Define target first, before everything else so that it is the
default.
(ps.exe): Don't add useless -lcygwin.
(ldh.exe): For consistency, add to existing MINGW_LDFLAGS rather than
redefining them.
(cygcheck.exe): Always include -lz for MINGW_LDFLAGS. Don't try to
figure out where to find it.
(dumper.exe): Simplify check. Assume libraries are installed rather
than trying to retrieve from source tree.
(install): Just use /bin/mkdir to create directories.
(Makefile): Regenerate when standard dependencies change.
* dump_setup.cc: Always include zlib.h. Remove accommodations for it
possibly not existing.
* parse_pe.cc: Add define which allows building with installed
binutils package.
* dumper.cc: Ditto.
