commit r10-11459-gf0f8cb2a9f6ec5fdfebb0ee15064133d36a91d64

libstdc++: include/bits/regex_error.h: Avoid warning with -fno-exceptions.
When building with -fno-exceptions, __GLIBCXX_THROW_OR_ABORT expands to
abort(), causing warnings:
unused parameter '__ecode'
unused parameter '__what'
This patch adds __attribute__((unused)) to avoid them.
