-/* Create a fundamental C type using default reasonable for the

-
- 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 disagreement 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 it's fundamental type information
- directly from the debugging information supplied by the compiler.
