Commit Message

These errors only show up when testing with -std=c++26 which isn't done
by default.

Tested x86_64-linux. Pushed to trunk.

Since r15-1794-gbeb7a418aaef2e the -Wdelete-incomplete diagnostic is a
permerror instead of a (suppressed in system headers) warning. Add
dg-error directives.

libstdc++-v3/ChangeLog:

	PR c++/115747
	* testsuite/tr1/2_general_utilities/shared_ptr/cons/43820_neg.cc:
	Add dg-error for new C++26 diagnostics.
