I am upgrading from 1.2.7 to 1.3.4 using essentially the same configuration options: ./configure --without-krb4 --enable-dns --enable-shared --enable-profiled --with-tcl=/usr/local The size of libkrb5.a (for example), went from 850kB to 10MB. My build environment: Solaris 9, gcc 3.2.1 Thanks for your time, Steve
