+Subject: [PATCH] fix libcap header issue on some distro
+
+1, When build qemu-native on SLED 11.2, there is an error:
+...
+| In file included from /usr/include/bits/sigcontext.h:28,
+| from /usr/include/signal.h:339,
+| from /buildarea2/tmp/work/i686-linux/qemu-native/1.4.0-r0/
+qemu-1.4.0/include/qemu-common.h:42,
+| from fsdev/virtfs-proxy-helper.c:23:
+| /usr/include/asm/sigcontext.h:28: error: expected specifier-
+qualifier-list before '__u64'
+| /usr/include/asm/sigcontext.h:191: error: expected specifier-
+qualifier-list before '__u64'
+...
+
+2, The virtfs-proxy-helper.c includes <sys/capability.h> and
+qemu-common.h in sequence. The header include map is:
+(`-->' presents `include')
+...
+"virtfs-proxy-helper.c" --> <sys/capability.h>
+...
+"virtfs-proxy-helper.c" --> "qemu-common.h" --> <signal.h> -->
+<bits/sigcontext.h> --> <asm/sigcontext.h> --> <linux/types.h> -->
+<asm/types.h> --> <asm-generic/types.h> --> <asm-generic/int-ll64.h>
+...
+
+3, The bug is found on SLED 11.2 x86. In libcap header file
+/usr/include/sys/capability.h, it does evil stuff like this:
+...
+ 25 /*
+ 26 * Make sure we can be included from userland by preventing
+ 27 * capability.h from including other kernel headers
+ 28 */
+ 29 #define _LINUX_TYPES_H
+ 30 #define _LINUX_FS_H
+ 31 #define __LINUX_COMPILER_H
+ 32 #define __user
+ 33
+ 34 typedef unsigned int __u32;
+ 35 typedef __u32 __le32;
+...
+This completely prevents including /usr/include/linux/types.h.
+The above `<asm/sigcontext.h> --> <linux/types.h>' is prevented,
+and '__u64' is defined in <asm-generic/int-ll64.h>.
+
+4, Modify virtfs-proxy-helper.c to include <sys/capability.h>
+last to workaround the issue.
