that contains a static instance of the class. * cp-valprint.c (dont_print_vb_obstack): Renamed from dont_print_obstack, made static. (dont_print_statmem_obstack): New obstack, controls printing of static member classes. (_initialize_cp_valprint): Initialize it. (cp_print_static_field): New function, handles printing of static members. (cp_print_value_fields): New parameter dont_print_statmem to handle recursive printing of static member classes, use cp_print_static_field to handle printing of static members. * c-valprint.c (cp_print_value_fields): Update prototype and call to include additional dont_print_statmem parameter. * c-valprint.c, f-valprint.c (dont_print_obstack): Remove unused extern declaration. * alpha-tdep.c, findvar.c, infptrace.c: Include <string.h>. * config/alpha/tm-alpha.h (FRAME_FIND_SAVED_REGS): Call alpha_find_saved_regs if fi->saved_regs is still NULL. * elfread.c (elf_symtab_read): Ensure that the filename field of a minsym is nonempty. Ignore solib trampoline symbols from the main symbol table, they might have a bogus value. * procfs.c (set_proc_siginfo), config/alpha/alpha-osf2.mh: Fix typos in comments.
