* 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...").
