Using .PHONY to suppress rebuilds of included makefile fragments

performance. I've never seen .PHONY used in this way, but from the gmake -d output I see it indeed does what he claims. Are there any reason why not to use .PHONY this way? Is there a better idiom to use to avoid rebuilds of Makefile fragments. Thanks in advance, --jtc -- J.T. Co

Is there any value in a lisp-like $(cond ...) function?

If so, I'll gladly contribute my func_cond implementation (even though there is nothing special about it -- almost all of it was taken from func_if and func_or). --jtc PS: And if I've totally missed a better idiom for this task, please let me know. -- J.T. Conklin __

directory order-only dependencies with trailing slash

One of my developers reported that our product's build fails with GNU make >= 3.82. I discovered the root cause of the issue was that we had order only prerequisites of directories with trailing slashes, but the targets used to create those directories did not. In our framework, these differenc
