How can make know whether the compiler/link on your system does something special with .l files, beyond the normal interpretation as lex files? Just out of curiosity, I tested the same thing with FreeBSD make > (`LDFLAGS=-ll make`) and it compiled `lang` as expected with this output: > The short answer is that FreeBSD make uses '$<' in the recipe of the applicable .c: pattern rule, while GNU make use '$^' in the parallel rule. Note that FreeBSD make doesn't actually require the dependency: you get the same results when the makefile is just lang: Philip Guenther
