* dbxread.c: Enable, but soften, const_vol_complaint.

Browse Source 
(read_dbx_symtab):  N_STSYM and N_LCSYM define static vars.
Ditto Gould N_NBSTS and N_NBLCS.  Also, all types in the psymtab
should be file-scope, not global.
(read_struct_type):  Remove ancient multiple-inheritance warning.
(read_range_type):  Check base type, complain & patch if undefined.
