            Bug ID: 30621
           Summary: compilers pretending to be gcc may break due to
                    __builtin___stpncpy_chk
           Product: glibc
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: string
          Assignee: unassigned at sourceware dot org
          Reporter: siddhesh at sourceware dot org
  Target Milestone: ---

The nvidia cuda compiler appears to[1] pretend to be gcc (or maybe clang) to
try and enable some features, but ends up enabling __builtin___stpncpy_chk even
when it doesn't implement that.  Fix up the macro checks in string_fortified.h
to handle this.
