DNEWS60 - support for Armv8-R aarch64 added
102 - K&R support removed in code and docs
DREADME7 Prior to the 3.0.0 release, newlib supported both ANSI and K&R-style
8 compilers. As of 3.0.0, K&R is no longer supported.
DChangeLog-20155857 (loadlocale): Map "KOI8-R" and "KOI8-U" to CP20866 and CP21866.
5861 * libc/stdlib/sb_charsets.c (__cp_conv): Add KOI8-R (Russian, CP20866)
