Re: [C] Re: [PACKAGES (tramp)] Another fsf-compat dependency bites the dust

No. These are _compile-time_ dependencies, and compilation is a file-at-a-time exercise. If you have an _explicit_ require in the file being compiled, then the compiler will do the require. However, people generally prefer to avoid explicit requires when they use the exported interface (ie, autoloaded functions), so that the libraries get pulled in only when a function that actually needs them is invoked. However, it turns out that it's possible to get yourself wedged into a situation where a needed macro or an efficient defsubst is not in the "clean" environment provided by the XEmacs package build system. And the clean environment does not provide the auto-autoloads (because they tend to mask insufficient requires or even pull in shadowing definitions from evil packages like APEL). So we need to require everything in sight. -- School of Systems and Information Engineering http://turnbull.sk.tsukuba.ac.jp University of Tsukuba Tennodai 1-1-1 Tsukuba 305-8573 JAPAN Ask not how you can "do" free software business; ask what your business can "do for" free software.
