+/* "Philosophy":
+
+   This suite tests the correct implementation of mathematical
+   functions in libm.  Some simple, specific parameters are tested for
+   correctness. Handling of specific inputs (e.g. infinity,
+   not-a-number) is also tested. Correct handling of exceptions is
+   checked against. These implemented tests should check all cases
+   that are specified in ISO C 9X.
+
+   Inline functions: Inlining functions should give an improvement in
+   speed - but not in precission. The inlined functions return
+   reasonable values for a reasonable range of input values. The
+   result is not necessarily correct for all values and exceptions are
+   not correctly raised in all cases. Problematic input and return
+   values are infinity, not-a-number and minus zero. This suite
+   therefore does not check these specific inputs and the exception
+   handling for inlined mathematical functions - just the "reasonable"
+   values are checked.
+
+   Beware: The tests might fail for any of the following reasons:
+   - Tests are wrong
+   - Functions are wrong
+   - Floating Point Unit not working properly
+   - Compiler has errors
+
+   With e.g. gcc 2.7.2.2 the test for cexp fails because of a compiler error.
