* minsyms.c (install_minimal_symbols): Add bunches to any
existing minsyms in the objfile. Avoid extra mallocation
by working directly in the obstack. Remove ignored `mainline' parm.
* coffread.c, dbxread.c, elfread.c, mipsread.c, solib.c, symtab.h,
xcoffread.c: Change all callers.
* FIXME: We should be able to eliminate MAINLINE from all the
symbol readers now, with a small bit of work.
* valops.c, value.h: Lint.
* remote-vx.c: Add missing break; statement. Bugfix by
Michael Sclafani, <sclafani@src.dec.com>.
