Sure, I am about to do so.
However I wasn't sure about this syntax before the commit so I had
run the new 2_neg.cc with:
make CXXFLAGS=-std=c++98 check-debug
and it worked fine and still is !
The testsuite doesn't use CXXFLAGS.
Did you mean CPPFLAGS ?
I do see the option added to the compiler call in libstdc++.log file.
And I used it to build for instance pretty-printers tests in
_GLIBCXX_DEBUG mode with success.
I also try -std=gnu++98 and made sure that pch had been updated by
re-building libstdc++ first. I just can't get the expected
compilation error.
Maybe I need to rebuild the whole stuff to get an error...
No, you need to pass the right flags so they are used by the
testsuite. This will do it:
make -C testsuite/ check-debug
debug_flags=unix/-D_GLIBCXX_DEBUG/-std=gnu++98/-Wsystem-headers
I'll have to keep your mail to remember it !
But since it only shows up with -Wsystem-headers, there's no point
trying to test for it.
Ok, makes sens.
Thanks
