-/* Create a fundamental C type using default reasonable for the current
-   target machine.
-
-   Some object/debugging file formats (DWARF version 1, COFF, etc) do not
-   define fundamental types such as "int" or "double".  Others (stabs or
-   DWARF version 2, etc) do define fundamental types.  For the formats which
-   don't provide fundamental types, gdb can create such types using this
-   function.
-
-   FIXME:  Some compilers distinguish explicitly signed integral types
-   (signed short, signed int, signed long) from "regular" integral types
-   (short, int, long) in the debugging information.  There is some dis-
-   agreement as to how useful this feature is.  In particular, gcc does
-   not support this.  Also, only some debugging formats allow the
-   distinction to be passed on to a debugger.  For now, we always just
-   use "short", "int", or "long" as the type name, for both the implicit
-   and explicitly signed types.  This also makes life easier for the
-   gdb test suite since we don't have to account for the differences
-   in output depending upon what the compiler and debugging format
-   support.  We will probably have to re-examine the issue when gdb
-   starts taking its fundamental type information directly from the
-   debugging information supplied by the compiler.  fnf@cygnus.com */
