Historically, we've tried to support all makes. At one time, the --srcdir support was broken with some makes, in particular Sun make, and I hacked the makefiles to fix this problem. Since then, all makes that support the (mostly undocumented) VPATH feature should work, with the exception that if you have done a build sans --srcdir, then a separate simultaneous build with --srcdir will lose in various interesting ways. VPATH is not part of the POSIX spec for make, and System V make, which introduced the feature, did not feel it was worth documenting. The engineer at Sun who added VPATH support (still without documentation!) to Sun make told me he had regretted adding this non-standard feature (to my utter dismay). Martin
