I don't remember whether Nathanael tried to contribute his macros to autoconf. I do agree they'd make sense. > Well, see how AM_INSTALL_LIBBFD is defined. ;-) Presumably you're configuring with --enable-shared --enable-install-libbfd. I'd never done that :-) Anyway, $(exec_prefix)/$(host_alias) is entirely pointless. $(exec_prefix) is already supposed to be host-specific. > Why is that so?

I can't think of any reason for that. But we're trying to move to autoconf 2.57, not some hacked version thereof, so we have to cope with its limitations for now. > Indeed, but I would prefer to see it done in autoconf so that it need not > be repeated locally elsewhere. It feels like you're volunteering to convert Nathanael's macros into autoconf, do I read it right? :-D :-D -- 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
