* Allow the stabs for long double to vary depending on DOUBLE_SZ.
*
* Revision 1.3 93/07/05 18:26:29 18:26:29 ra (Robert Andrews)
* A couple of minor corrections. Introduced stab_ptrs to avoid duplication
* of basic pointer types.
*
* Revision 1.2 93/06/29 14:32:54 14:32:54 ra (Robert Andrews)
* Fairly major rewrite and reformat. There were a number of errors which
