            Bug ID: 21304
           Summary: make check fails with /usr/bin/install: cannot remove
                    '/usr/include/stdlib.h': Permission denied
           Product: glibc
           Version: 2.24
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: nptl
          Assignee: unassigned at sourceware dot org
          Reporter: nszabolcs at gmail dot com

  Target Milestone: ---

bug 20314 is not fixed: libstdc++ added std_abs.h which has the same issue. (i
noticed it when running make check a second time in the same build directory,
not sure why it works for the first time, but this is a nasty issue:

make  subdir=nptl -C nptl ..=../ tests
make[2]: Entering directory `SRC/nptl'
/usr/bin/install -c -m 644 ../include/stdlib.h /usr/include/stdlib.h
/usr/bin/install: cannot remove '/usr/include/stdlib.h': Permission denied
make[2]: *** [/usr/include/stdlib.h] Error 1

and preprocessing nptl/tst-thread_local1.cc reveals that indeed std_abs.h
caused include_next <stdlib.h> to find /usr/include/stdlib.h and thus it gets
added to the make deps)

instead of playing whack a mole with libstdc++ headers, glibc should stop
including things into its tests that are not under the control of glibc (i see
no reason to create c++ threads to test c++ destructor semantics) and the
workaround hack in commit 9be4ecc5bbecb2fdbeee0c0d7af30e94517fd5d6 should be
reverted.
