898 define fundamental types.
900 For the formats which don't provide fundamental types, gdb can create

903 FIXME: Some compilers distinguish explicitly signed integral types
904 (signed short, signed int, signed long) from "regular" integral types
905 (short, int, long) in the debugging information. There is some dis-
906 agreement as to how useful this feature is. In particular, gcc does
907 not support this. Also, only some debugging formats allow the
908 distinction to be passed on to a debugger. For now, we always just
909 use "short", "int", or "long" as the type name, for both the implicit
910 and explicitly signed types. This also makes life easier for the
911 gdb test suite since we don't have to account for the differences
912 in output depending upon what the compiler and debugging format
913 support. We will probably have to re-examine the issue when gdb
