My question is about a comment in GCC 5.2.0's Makefile (reproduced below). I don't understand how adding ": $(MAKE) ;" before the "$(unstage)" avoids warnings from the GNU Make job server. AFAIK, the :$(MAKE) ; basically behaves like a comment. What difference will it make to the job server ? What kind of warning does it avoid ?
# While making host and target tools, symlinks to the final stage must be # there, so $(unstage) should be run at various points. To avoid excessive # recursive invocations of make, we "inline" them using a variable. These # must be referenced as ": $(MAKE) ; $(unstage)" rather than "$(unstage)" # to avoid warnings from the GNU Make job server. _______________________________________________ Help-make mailing list Help-make@gnu.org https://lists.gnu.org/mailman/listinfo/help-make
