Autoconf used to have AC_INCLUDE, but it got removed in 2.49a. Apparently, it got replaced with autoreconf --install, I guess under the theory that everybody who wanted this sort of thing would be using aclocal. Sorry, I didn't know about autoreconf --install until just now, or I'd have mentioned it earlier. And I don't know exactly what it does; you may have to look at the source to figure it out. Perhaps Akim can chime in and explain the motivation here; I'm a bit out of my depth. > * If a macro exists in both the site macro directory and the `m4' > subdirectory, the version in the site macro directory will be > copied over the version in the `m4' subdirectory. I would say that only --install should copy; the default should be to use a search path, without copying. > * If the same macro is defined in both aclocal.m4 and in the site > macro directory (or the `m4' subdirectory), the version in > aclocal.m4 takes precedence. But the aclocal command typically produces aclocal.m4 from the m4 subdirectory. (acinclude.m4 is obsolete.)
