as all functions that call vscanf, vfscanf, or vsscanf are annotated with
__attribute__ ((format (scanf, ...))).
+* A future release of glibc will use a 64-bit off_t type on all
+ architectures (as currently available with -D_FILE_OFFSET_BITS=64 on
+ 32-bit architectures). Building new applications with
+ -D_FILE_OFFSET_BITS=32 will no longer be supported. The off64_t type and
+ the 64-bit function aliases (such as fstat64) will remain available under
+ the appropriate feature test macros. In preparation, libraries should
+ stop using off_t in public header files, and use off64_t (or a fixed-width
+ type such as int64_t or uint64_t) instead.
Changes to build and runtime requirements:
* Python 3.4 or later is required to build the GNU C Library.
