Anyone running Debian who's interested in working on this, try # apt-get install gcc-3.3 $ cd src/guile/head/ $ CC=gcc-3.3 ./configure ... $ make clean $ make This shouldn't affect your existing gcc 3.2 install, i.e. gcc --version should still give you 3.2... We use -Wall -Werror by default now (in the unstable branch), so you'll get those options automatically. From an initial test, it looks like we've at least got a new slew of signed/unsigned compare warnings. -- Rob Browning rlb @defaultvalue.org, @linuxdevel.com, and @debian.org Previously @cs.utexas.edu GPG starting 2002-11-03 = 14DD 432F AE39 534D B592 F9A0 25C8 D377 8C7E 73A4 _______________________________________________ Guile-devel mailing list Guile-devel@gnu.org http://mail.gnu.org/mailman/listinfo/guile-devel
