the new test FAILs to link on Solaris 10:
+FAIL: gcc.dg/strlenopt-46.c (test for excess errors)
+UNRESOLVED: gcc.dg/strlenopt-46.c compilation failed to produce executable
Excess errors:
Undefined first referenced
symbol in file
strnlen /var/tmp//ccyrOY3M.o
ld: fatal: symbol referencing errors. No output written to ./strlenopt-46.exe
