In commit
be586d53b I made empty.h depend on $(allsources), which
unfortunately was defined so as to include empty.h. This was harmless,
because make just ignored the circular dependency, but annoying,
because it constantly mentioned that it was ignoring it.
# auto-generated parts of this makefile, but Recipe might like to
# have it available as a variable so that mandatory-rebuild things
# (version.o) can conveniently be made to depend on it.
- @sources = ("allsources", "=", sort keys %allsourcefiles);
+ @sources = ("allsources", "=",
+ sort grep {$_ ne "empty.h"} keys %allsourcefiles);
print &splitline(join " ", @sources), "\n\n";
@cliprogs = ("bin_PROGRAMS", "=");
