Package: g++-10
Version: 10.2.1-6
Severity: important
X-Debbugs-Cc: um4711@mutluit.com

Dear Maintainer,

the value std::regex_constants::multiline is supposed to be present
in C++17 and later (cf. for example https://en.cppreference.com/w/cpp/regex/basic_regex/constants ),
but actually it's missing in this compiler version (which supports C++17 as well even C++20).

Compiler switches used:
OPTS="-Wall -Wextra -W -Wformat -pedantic -pedantic-errors -std=gnu++20 -frecord-gcc-switches"
g++ -g $OPTS blahfoo.cpp -lm -lssl -lcrypto -lz

The compilation error:
"
blahfoo.cpp:5122:59: error: ‘multiline’ is not a member of ‘std::regex_constants’
 5122 |         if (sOpt == "multiline")  { f |= regex_constants::multiline; continue; }
      |                                                           ^~~~~~~~~
Command exited with non-zero status 1
"

$ g++ --version
g++ (Debian 10.2.1-6) 10.2.1 20210110

Expectation:
Since this compiler version supports C++17 (and even C++20), then it should have
the above said missing C++17 constant defined.
