* dbxread.c (end_psymtab): Only reset texthigh if it's not already
set. Don't reset our own texthigh, or dependency-only pst's, in
scanning all the rest of the psymtabs.
(process_one_symbol): Fix comments around N_OBJ, N_OPT, N_UNDF.
* buildsym.h (N_UNDF): Improve comments.
(N_LSYM, etc): Skip types without names (":T(0,3)=sfoob...").
