Yes, I agree with that, and I am still going to do that. You opened two bug reports originally (inadvertently), I only closed the one that was dealt with.

I don't think that is correct. In fact, I think it is entirely intended to be possible to use a different prefix= setting for the all and for the install targets, and the latter should still not rebuild sources. Sort of a poor-man's DESTDIR. You can see the usefulness on MSYS and DJGPP (where DESTDIR does not work due to drive prefix concatenation). (Of course Libtool doesn't support the non-DESTDIR way, but that's another story ...) Cheers, Ralf
