Not ok. athlon-linux-gnu is canonicalized to i686-linux-gnu, so we can't use the same directories for both of them. (Consider building a compiler on athlon that must run on i686, or on the other way round). I see where you're coming from, but we're really going to have to bite the bullet and duplicate autoconf 2.5x's behavior WRT machine name variables, or convince autoconf folks to give us some means to obtain the defaulted values, which shouldn't be too hard. Say, if configure could set {build,host,target}_noncanonical to whatever autoconf 2.13 used to set as {build,host,target}_alias, we'd be all set. Bonus points of they actually agree to go back to setting the _alias variables in a backward-compatible way, while setting _cmdline to whatever was passed in the command line. -- Alexandre Oliva Enjoy Guarana', see http://www.ic.unicamp.br/~oliva/ Red Hat GCC Developer aoliva@{redhat.com, gcc.gnu.org} CS PhD student at IC-Unicamp oliva@{lsd.ic.unicamp.br, gnu.org} Free Software Evangelist Professional serial bug killer
