Well, using my patches to the makefiles, you can: Just by unpacking
the djlsr distribution .zip to somewhere else than $(DJDIR) (and maybe 
changing the line setting MY_LIBGCC_A in makefile.def), you can build
them without overwriting anything at all.

My original diffs from July went one step further: they wrote nothing to
any place up-tree of the 'src' directory during the 'make' run. Everything
was built in src/{bin,lib,info,include}, and only by calling 'make
install' it would be transferred to the actual target location.

Given enough interest (i.e.: a good chance that it'll make it into the
distributed version), I might re-implement that trick for the current
setup. DJ?

Good point. Building a 586-optimized lib for experimental purposes might
be another interesting idea along these lines. Generally, experimental
builds should never overwrite the production versions.
