+/* This header is internal to glibc and should not be included outside

+ global declarations that may or may not already have been made by a
+ header provided by the underlying operating system kernel. All such
+ declarations are associated with macros named __UAPI_DEF_something,
+ which have three possible values:
+
+ If __UAPI_DEF_FOO is not defined, nobody has yet declared `foo'.
+ If __UAPI_DEF_FOO is defined to 0, glibc's headers have declared `foo'.
+ If __UAPI_DEF_FOO is defined to 1, the kernel's headers have declared `foo`.
+
+ This header cannot have a multiple-inclusion guard, because it needs
+ to recheck for additional declarations by kernel headers each time
+ a glibc header that uses it is included.
+
+ This generic version of uapi-compat.h is used on operating systems
+ where none of the above coordination is necessary. */

+ a glibc header that uses it is included.
+
+ This version of uapi-compat.h is used for Linux. Sufficiently new
+ versions of the Linux kernel headers will define the __UAPI_DEF_*
+ macros themselves; this header's job is to preserve compatibility
+ with older versions of the headers that don't do this.
+
+ The guard macros on many of Linux's UAPI headers were changed in
+ kernel rev 56c176c9; we need to check them both with and without a
+ _UAPI_ prefix. */
