In r16-4709-gc55c1de3a9adb2 I meant to use the result of the
static_cast<char> for the rest of the function following it, but I
accidentally used the original variable __ch. This causes
-Wunused-variable warnings for the __c initialized from the cast.
This fixes the rest of the function to use __c instead of __ch.
libstdc++-v3/ChangeLog:
* include/bits/regex.tcc (regex_traits::value): Use __c instead
of __ch.
