So you run make b and get "b" like you expected. Cool. Then you try dmake -s b thinking it'll do the same thing, and suddenly target 'a' decides to run first and you get "a" followed by "a: no action was taken." Welcome to the wonderful world of build systems where POSIX compliance is more of a suggestion than a rule. Different make implementations parse dependencies differently, and dmake (Sun's make) apparently has its own ideas about how your Makefile should work. Same file, same rules, completely different execution order. It's like having two compilers that interpret the same code differently—which, let's be honest, also happens more than we'd like to admit. The real fun starts when your CI/CD pipeline uses a different make implementation than your local machine. Good times.
