No. The bit of commentary mentioning MacOS's very old 'make' was just
talking about a possible alternate way of implementing the change.
That alternative was not chosen, so talking about old 'make' in the
commit message would be confusing for readers. More importantly,
although that alternative would have made a less noisy patch, the
actual result would have made the Makefile itself noisier and uglier,
particularly for people just reading the Makefile in the future,
people who did not read the patch. Specifically, these alternatives
were considered:
ifdef NO_ICONV
undefine NEEDS_LIBICONV
endif
ifdef NEEDS_LIBICONV
...as before...
endif
and:
ifdef NO_ICONV
NEEDS_LIBICONV=
endif
ifeq ($(NEEDS_LIBICONV),)
...as before...
endif
Both of which are uglier for a future reader of Makefile than the
end-result actually implemented by this patch:
ifndef NO_ICONV
ifdef NEEDS_LIBICONV
...as before...
endif
endif
