The tail call is optimized, meaning now mmin/mtime just prepare arguments and jump into the common code, thus near zero overhead. This reduces code size slightly, e.g. on x86_64: text data bss dec hex filename 4806 0 0 4806 12c6 findutils/find.o.orig 4782 0 0 4782 12ae findutils/find.o Of course, the savings are even greater when implementing atime/ctime variants.
