* math/w_exp_compat.c: Replace hidden_def with libm_hidden_def..
* The tilegx*-*-linux-gnu configurations are no longer supported.
+* The obsolete function ustat is no longer available to newly linked
+ binaries; the headers <ustat.h> and <sys/ustat.h> have been removed. This
+ function has been deprecated in favor of fstatfs and statfs.
