+This testsuite consists of a collection of (non-functional) programs snippets 
+to check an RTEMS toolchain consisting of 
+* GCC (libgcc etc.)
+* binutils
+* newlib (libc)
+* RTEMS (librtemscpu + librtemsbsp)
+for IEEE Std 1003.1-2008 (aka. POSIX[1]) compliance by link-tests.
+
+All of these programs are supposed to be compilable without any warning,
+independently of the configuration being used in any of the components
+involved.
+
+NB: 
+- Using "advanced GCC warning flags" may trigger warnings. Such warnings
+  should be avoided if possible.
+
+- These program snippets are not supposed to be functional.
+
+- This suite only checks for a subset of POSIX library calls, which are
+  known to have been critical in RTEMS/GCC/newlib interaction at some point
+  in RTEMS/GCC/newlib's history.
+
+References:
+[1] The Open Group Base Specifications Issue 7, IEEE Std 1003.1™-2008,
