--------------------------------+-------------------------------------------
 The gcc45 (and 46) build should by default activate --enable-plugin and
 --enable-lto options. The latter triggers link time optimization that can
 be used to further optimize binaries. Both are required to build
 dragonegg.

 Also gcc46 should be updated to 4.6.1 instead of the last ß-version.
