+/** rough characterization of compiler and native C library
+For the compiler, it can either support long double or not. If it doesn't, the
+macro _STLP_NO_LONG_DOUBLE is not defined and we don't define any long double
+overloads.
+For the native C library the question is whether it has variants with an 'f'
+suffix (for float as opposed to double) or an 'l' suffix (for long double). If
+the float variants are missing, _STLP_NO_VENDOR_MATH_F is defined, when the
+long double variants are missing, _STLP_NO_VENDOR_MATH_L is defined. Of course
+the latter doesn't make sense anyway when the compiler already has no long
+double support.
+
+Those two traits determine a) which overloads get defined and b) how they are
+defined.
+
+Meaning of suffixes:
+""   : function returning and taking a float_type
+"2"  : function returning a float_type and taking to float_types
+"2P" : function returning a float_type and taking a float_type and a float_type*
+"2PI": function returning a float_type and taking a float_type and an int*
+"2I" : function returning a float_type and taking a float_Type and an int
