Usually I do weekly build configuring with:

${gcc_dir}/configure --prefix=/usr/local/gfortran
--exec-prefix=/usr/local/gfortran --sysconfdir=/usr/local/gfortran/etc
--libdir=/usr/local/gfortran/lib --libexecdir=/usr/local/gfortran/lib
--mandir=/usr/local/gfortran/share/man
--infodir=/usr/local/gfortran/share/info --program-suffix=-4.4
--enable-languages=c,fortran --enable-bootstrap
--enable-decimal-float=bid --enable-libgomp --enable-threads
--enable-sjlj-exceptions --enable-version-specific-runtime-libs
--enable-nls --enable-checking=release --disable-fixed-point
--disable-libmudflap --disable-shared --disable-win32-registry
--with-system-zlib --without-included-gettext --without-x
