-/* Output floating point type values used by the 'R' stab letter.
-   These numbers come from include/aout/stab_gnu.h in binutils/gdb.
-
-   There are only 3 real/complex types defined, and we need 7/6.
-   We use NF_SINGLE as a generic float type, and NF_COMPLEX as a generic
-   complex type.  Since we have the type size anyways, we don't really need
-   to distinguish between different FP types, we only need to distinguish
-   between float and complex.  This works fine with gdb.
-
-   We only use this for complex types, to avoid breaking backwards
-   compatibility for real types.  complex types aren't in ISO C90, so it is
-   OK if old debuggers don't understand the debug info we emit for them.  */
