bug#8845: build failure on HP-UX 11.31

[Bruno Haible]

Trying to compile coreutils-8.12 on HP-UX 11.31 with cc, I get this build
failure:


  CC       file-set.o
cc: "file-set.h", line 9: error 1000: Unexpected symbol: "2".
cc: "file-set.h", line 7: error 1670: Illegal attribute nonnull specified.
gmake[4]: *** [file-set.o] Error 1


Here's a possible patch that fixes it.


2011-06-13  Bruno Haible  <address@hidden>

        Update after __attibute__ is no longer defined by gnulib.
        * lib/file-set.h (record_file): Use __attribute__ only with compiler
        versions that support it.
