198 For the compiler, it can either support long double or not. If it doesn't, the
199 macro _STLP_NO_LONG_DOUBLE is not defined and we don't define any long double
201 For the native C library the question is whether it has variants with an 'f'
202 suffix (for float as opposed to double) or an 'l' suffix (for long double). If
203 the float variants are missing, _STLP_NO_VENDOR_MATH_F is defined, when the
204 long double variants are missing, _STLP_NO_VENDOR_MATH_L is defined. Of course
205 the latter doesn't make sense anyway when the compiler already has no long
208 Those two traits determine a) which overloads get defined and b) how they are
