--disable-cloog-version-check
disable check for CLooG version
--enable-lto enable link time optimization support
+ --enable-linker-plugin-configure-flags=FLAGS
+ additional flags for configuring linker plugins
+ [none]
+ --enable-linker-plugin-flags=FLAGS
+ additional flags for configuring and building linker
+ plugins [none]
--enable-stage1-languages[=all]
choose additional languages to build during stage1.
Mostly useful for compiler development
--enable-objc-gc enable use of Boehm's garbage collector with the GNU
Objective-C runtime
+ --enable-vtable-verify Enable vtable verification feature
--enable-serial-[{host,target,build}-]configure
force sequential configuration of sub-packages for
the host, target or build machine, or all
choose additional checking for stage1 of the
compiler
--enable-werror enable -Werror in bootstrap stage2 and later
+ --enable-host-shared build host code as shared libraries
