             Bug #: 13966
           Summary: Some elf tests fail with "fatal error: cstdio: No such
                    file or directory" on trunk
           Product: glibc
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: build
        AssignedTo: unassigned@sourceware.org
        ReportedBy: cryptooctoploid@gmail.com

    Classification: Unclassified


For example:

/var/tmp/glibc-build/elf/tst-unique3lib.os.dt -MT
/var/tmp/glibc-build/elf/tst-unique3lib.os
tst-unique3lib.cc:1:18: fatal error: cstdio: No such file or directory
compilation terminated.

This is apparently caused by the -nostdinc flag; without it the problem
vanishes.
