+ Improve support for SunPro F77.
+ * dbxread.c (end_psymtab, process_one_symbol): Handle minimal
+ symbols with trailing underscore names.
+ * minsyms.c (find_stab_function_addr): Ditto.
+ * dbxread.c (process_one_symbol): Ignore N_ALIAS for now.
+ * partial-stab.h (case N_ALIAS): Ditto.
+ * stabsread.c (read_sun_builtin_type): Handle boolean types.
