We have a configure.ac check for lib.exe that attempts to enable
creation of .lib files for our 5 public libraries. That has been broken
for a long time for two reasons:
1) the Makefiles hardcode 'lib' instead of 'lib.exe'
2) we dropped generation of .def files quite some time ago (except for
in gthread where we have the two-symbol file under version control)
Add new rules for creating .def files from dumpbin.exe (which you should
have if you have lib.exe) and fix the .lib rules to use lib.exe.
Add a bit of $(AM_V_GEN) all around, as well.

Perform a substantial cleanup of the build system with respect to
building and installing testcases.
First, Makefile.decl has been renamed glib.mk and substantially
expanded. We intend to add more stuff here in the future, like canned
rules for mkenums, marshallers, resources, etc.
By default, tests are no longer compiled as part of 'make'. They will
be built when 'make check' is run. The old behaviour can be obtained
with --enable-always-build-tests.
--disable-modular-tests is gone (because tests are no longer built by
default). There is no longer any way to cause 'make check' to be a
no-op, but that's not very useful anyway.
A new glibtests.m4 file is introduced. Along with glib.mk, this
provides for consistent handling of --enable-installed-tests and
--enable-always-build-tests (mentioned above).
Port our various test-installing Makefiles to the new framework.
This patch substantially improves the situation in the toplevel tests/
directory. Things are now somewhat under control there. There were
some tests being built that weren't even being run and we run those now.
The long-running GObject performance tests in this directory have been
removed from 'make check' because they take too long.
As an experiment, 'make check' now runs the testcases on win32 builds,
by default. We can't run them under gtester (since it uses a pipe to
communicate with the subprocess) so just toss them in TESTS. Most of
them are passing on win32.
Things are not quite done here, but this patch is already a substantial
improvement. More to come.
Some (broken) toolchains for example trip up
-Werror=missing-prototypes in system headers. This patch allows
people to skip the formerly hardcoded "baseline" warnings.

We only want to control the default visibility for our five main
installable libraries: libglib, libgthread, libgmodule, libgobject,
libgio. We should therefore only set -fvisibility=hidden when building
those.
Use a separate substitution variable for this purpose.
Using CFLAGS directly leads to some modules built in testcases not
exporting their symbols (and then the tests fail). It also affects the
fam file monitoring module.
Colin had originally done it this way in his visibility patch series but
I failed to understand why so I didn't copy it. Now I do.
Also: revert changes made to two testcases in an attempt to work around
this issue.

One of the features of our new symbol exporting regime is that it forces
config.h to be included at the top of every .c file.
This was missed in gthread-impl.c.
The only reason this wasn't noticed is because nothing in this file is
being used anymore. We need those symbols to continue to be exported
for reasons of ABI backwards compatibility, however.
This was turning all the GLIB_VARs in the glib headers into
dllexports on windows, causing all sort of nastiness. libgthread is
mostly empty now anyway, so we don't need any GLIB_COMPILATION like
flag.
g_thread_init() is now a deprecated API, so drop G_DISABLE_DEPRECATED
from the CFLAGS for gthread/. Add the missing declaration for
g_thread_init_with_errorcheck_mutexes() back to deprecated/gthread.h.
And remove the 'joinable' argument from g_thread_new() and
g_thread_new_full().
Change the wording in the docs. Clarify expectations for
(deprecated) g_thread_create().
configure.ac defined G_THREAD_SOURCE and gthread-impl would #include it.
Instead, since we only have two thread implementations now, and since we
always use the Windows one only on Windows, move the logic to the
Makefile, predicated on 'if OS_WIN32'. Then have the chosen backend do
the #include "gthread-impl.c" from there.
Remove the G_THREAD_SOURCE define from configure.ac.
The translation of GLib priorities into the thread priorities of
different operating systems belongs in the implementation -- not
half-way in the front end.
g_thread_gettime() is an undocumented public function pointer that
points to a function that returns the monotonic time in nanoseconds.
g_get_monotonic_time() does the same in microseconds, so it can be used
instead.
GLib had one internal user in GFileMonitor that only cared about
millisecond accuracy; it has been ported to g_get_monotonic_time().
G_THREADS_ENABLED still exists, but is always defined. It is still
possible to use libglib without threads, but gobject (and everything
above it) is now guaranteed to be using threads (as, in fact, it was
before, since it was accidentally impossible to compile with
--disable-threads).

We need to test the case of eventfd in the libc but no kernel support.
In order to do that, we add a separate compile of the GWakeup testcase
that interposes an 'eventfd' symbol that always returns -1 with errno
set. That will trigger the fallback case.
