+ regex: simplify Gnulib port
+ This simplifies the code, by removing stuff intended for porting
+ to Gnulib but no longer needed there.
+ * posix/regcomp.c [!_LIBC]: No need to put #ifdef _LIBC around
+ uses of libc_hidden_def, weak_alias.
+ * posix/regcomp.c, posix/regexec.c: Use __restrict rather than
+ _Restrict_ except for public-facing headers.
+ * posix/regex_internal.h (attribute_hidden) [!_LIBC]:
+ Remove; already defined elsewhere.
+ * posix/regex.c, posix/regex_internal.h:
+ Use __GNUC_PREREQ instead of rolling our own.
+ * posix/regex_internal.h (__GNUC_PREREQ): Remove duplicate defn.

* benchtests/bench-strlen.c (generic_strlen): New function.
