eventfd(7) uses less resources than a pipe, as it only needs to store a
single 64-bit integer, as opposed to a full buffer.
It was introduced first on Linux version 2.6.22 and glibc 2.7. However,
both the configure-time test and the runtime usage require the use of
EFD_CLOEXEC for thread-safety, so this code will be enabled only for
Linux 2.6.27 and up as well as glibc 2.9 and up.

Adding the files from
libxcb-proto (version 0.1.6), compiled with libxcb-1.5
xcb-util (version 0.3.9)
xcb-util-image (version 0.3.9)
xcb-util-keysyms (version 0.3.9)

xcb-util-wm (version 0.3.9)

Adding a configure option '-qt-xcb' to use the sources instead of
linking to the respective runtime libraries.

The error comes from the Q_FOREACH expansion. Note that Q_FOREACH uses

goes and defines the GCC "safe" macro (double underscores on both

For some reference platforms and SDKs we will need to pass in

This change introduces the -device <name> and -device-option
<key=value> option. The key value pairs will be written to a
qdevice.pri and can be used by the qmake.conf of the device spec.
The reason to not save the key value pairs in qconfig.pri is
becase of the fact that the device spec loads the qdevice.pri
earlier than the qconfig.pri. qdevice.pri allows the mkspec
to set the compiler flags and qconfig.pri allows configure to
add to those compiler flags.

Set QT_ARCH and QT_HOST_ARCH qconfig.pri variables based on the compiler
target. This is done by running qmake (twice when cross-compiling) on
config.tests/arch/arch.pro, which preprocesses a file that contains all
knowns processors.
On Windows, configure.exe has never run any config.tests before, and
does not currently have a function to run a program and capture its
output. Use _popen() to accomplish this (as qmake does for its system()
function). This needs to be done after qmake is built, as does the
mkspecs/qconfig.pri generation. As a side effect, the configure steps
have been slightly re-ordered, but the overall result is the same. The
displayConfig() call is moved to just before generating Makefiles, so
that it can show the detected architecture(s).
