Often, orte/util/show_help.h is included, although no functionality is required -- instead, most often opal_output.h, or orte/mca/rml/rml_types.h Please see orte_show_help_replacement.sh commited next. - Local compilation (Linux/x86_64) w/ -Wimplicit-function-declaration actually showed two *missing* #include "orte/util/show_help.h" in orte/mca/odls/base/odls_base_default_fns.c and in orte/tools/orte-top/orte-top.c Manually added these. Let's have MTT the last word. This commit was SVN r20557.
