* On GNU/Linux, the obsolete Linux constant PTRACE_SEIZE_DEVEL is no longer
defined by <sys/ptrace.h>.
+* libm no longer supports SVID error handling (calling a user-provided
+ matherr function on error) or the _LIB_VERSION variable to control error
+ handling. (SVID error handling and the _LIB_VERSION variable still work
+ for binaries linked against older versions of the GNU C Library.) The
+ libieee.a library is no longer provided. math.h no longer defines struct
+ exception, or the macros X_TLOSS, DOMAIN, SING, OVERFLOW, UNDERFLOW,
+ TLOSS, PLOSS and HUGE.
