[DTrace-devel] [PATCH] test: Account for variations in error messages

From: Eugene Loh <eugene.loh at oracle.com>

Clearly,
    test/unittest/enum/err.*RepeatIdentifiers.d
    test/unittest/types/err.*dupenum.d
are impacted, but so are
    test/unittest/offsetof/err.D_UNKNOWN.OffsetofNULL.d
    test/unittest/types/err.D_UNKNOWN.dupstruct.d
    test/unittest/union/err.D_DECL_INCOMPLETE.circular.d
    test/unittest/union/err.D_DECL_INCOMPLETE.order.d
    test/unittest/union/err.D_DECL_INCOMPLETE.simple.d
due to symlinks to libctf.r.p.  And dupstruct needed a fix.
