Oh,  yes, I don't use this option. I only see the documentation said we 
can use ./configure and make instead of make all in the openposix 
direcotry. But miss this  --with-open-posix-testsuite option .


I think we should mention this option in README ie


./configure --with-open-posix-testsuite --with-realtime-testsuite
diff --git a/README.md b/README.md
index d45d1ee44..7da393e37 100644

  $ ./configure

+If you want to include open posix testsuite or realtime testsuite, the 
chances are
+the following will work:
+
+```
+$ ./configure --with-open-posix-testsuite --with-realtime-testsuite
+```
+
  Now you can continue either with compiling and r
