GCC 4.6.0 will include the +libquadmath library, which provides quad-precision mathematical +functions on targets supporting the __float128 datatype.

Would you mind using ... instead of ... and making this a link to gcc-4.6/changes.html#libquadmath (adding that as an id="libquadmath" at the changes.html page)? How about changing the last two sentences The library is used to provide on such targets the REAL(16) type in GNU Fortran compiler. The library has been contributed by François-Xavier Coudert. to The library is used to provide the REAL(16) type on such targets. It has been contributed by François-Xavier Coudert. ?
