            Bug ID: 101228
           Summary: #include <execution> triggers Intel TBB warning for
                    tbb/task.h
           Product: gcc
           Version: 11.1.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: libstdc++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: kip at thevertigo dot com
  Target Milestone: ---

I've managed to reproduce this issue on two different machines, one amd64 and
the other ppc64le. Both were using g++-11 (Ubuntu 11.1.0-1ubuntu1~21.04)
11.1.0.

Here is a minimal:

#include <algorithm>
#include <execution>

using namespace std;

int main()
{
    vector<long int> Container(3'000'000);
    iota(begin(Container), end(Container), 1);

    sort(execution::par, begin(Container), end(Container));

    return 0;
}

Compiling raises the following pragma in header generated warning:

$ g++-11 test.cpp -o test -Wall -Werror -std=c++17 -ltbb && ./test
In file included from /usr/include/c++/11/pstl/parallel_backend_tbb.h:26,
                 from /usr/include/c++/11/pstl/parallel_backend.h:20,
                 from /usr/include/c++/11/pstl/algorithm_impl.h:22,
                 from /usr/include/c++/11/pstl/glue_execution_defs.h:50,
                 from /usr/include/c++/11/execution:32,
                 from test.cpp:4:
/usr/include/tbb/task.h:21:139: note: ‘#pragma message: TBB Warning: tbb/task.h
is deprecated. For details, please see Deprecated Features appendix in the TBB
reference manual.’
   21 | ("TBB Warning: tbb/task.h is deprecated. For details, please see
Deprecated Features appendix in the TBB reference manual.")
      |                                                                        
                                                   ^

Compiling again with #define TBB_SUPPRESS_DEPRECATED_MESSAGES 1 prepended to
the beginning and the warning disappears.

This appears to have crept in some how with the 11 series. The <execution>
header is indirectly including some deprecated Intel header from the TBB
library.
