I think we could try to replace the libtool by our own stripped-down implementation that will be even simpler than dolt. If dolt is able to reduce the compilations speed by about one forth, then with a FreeBSD specific libtool replacement the imporvement may be even better. As a benefit we can also stop installing .la and .a library files. -- Stanislav Sedov ST4096-RIPE !DSPAM:49f23d66967006995215746!
