If you do just ./configure;make;make install, cc will be invoked without any optimization: ... gcc -DHAVE_CONFIG_H -DDEFAULT_CONFIG_FILE=\"/etc/squid.conf\" -I. -I../../src -I../include -I. -I../../src -I../include -I../../include -c `test -f ../../src/store_rebuild.c || echo '../../src/'`../../src/store_rebuild.c ... Setting CFLAGS="-O2" (hmm... I prefer -Os!) helps, but it's better be a default, no? -- vda
