When we build neither any system emulation targets nor the tools there
is actually no need for pixman library.  In that case do not enforce
presence of that library on the system.

vnc-tls.h is included by vnc.h, and it includes gnutls/gnutls.h.
Hence, GnuTLS header files are needed by all files that include

Default to 'cc' as our compiler, rather than 'gcc'. We used to have
to insist on gcc when we still kept the CPU env in a fixed global
register, but this is no longer necessary and we will now compile OK
on clang as well as gcc.  Using 'cc' should generally result in us
using the most standard and maintained system compiler for the
platform.  (For instance on newer MacOS X 'gcc' exists but is an
elderly compiler provided mostly for legacy reasons, and 'cc'
(which is clang) is definitely the better choice.) On Linux there
will generally be no user-visible change since cc will be gcc.

This changeover necessitates a slight reworking of how we set the
'cc' variable, because GNU cross toolchains generally provide a
'${cross_prefix}gcc' but not a '${cross_prefix}cc'.

gcc will silently accept unrecognized -Wno-wombat warning suppression
options (it only mentions them if it has to print a compiler warning
for some other reason). Since we already run a check for whether gcc
recognizes the warning options we use, we can easily make this use
the positive sense of the option when checking for support for the
suppression option. This doesn't have any effect except that it avoids
gcc emitting extra messages about unrecognized command line options
when it is printing other warning messages.

Disable clang's initializer-overrides warnings, as QEMU makes significant
use of the pattern of initializing an array with a range-based default
entry like

would otherwise warn "initializer overrides prior initialization of

revision to 4.  The new features available require a recent spice-server

The usbredir 0.5 release introduced the new API for 64 bit packet ids, but
it kept the libusbredirparser.pc name as is, meaning that older versions of
qemu will still have their pkg-config check for usbredirparser fulfilled,
and build with the usb-redir device. Due to the API change there will be
some compiler warnings, but the build will succeed, however the usb-redir
device will be broken on 32 bit machines.

To solve this a new usbredir-0.5.2 release is coming, which renames the
libusbredirparser.pc file to libusbredirparser-0.5.pc, so that it will no
longer fulfill the pkg-config check of the qemu-1.2 and older releases,
stopping the (silent) breakage. This patch adjusts qemu master's configure
to properly detect the new usbredir release.

Changes in v2:
-Not only use the new .pc name in the check but also when getting cflags
 and libs!
