Truly speaking I want to use this functionality to link basesystem with alternative malloc(9) implementation, just like this from libefence. This is how I discovered one of the allocation problems in FreeBSD basesystem. Doing this kind of tests does not work in some cases when LD_* variables are used. Looking at recent posts, I think new malloc implementation (patch posted by Jason Evans) could also be tested in this way. I also use SENDMAIL_* macros and although difficulties you've written about, choice. I think it's advantage to have them. And please note, that it's system administrator choice to play with custom libraries. -- * Wojciech A. Koszek && dunstan@FreeBSD.czest.pl
