I don't like actually naming a specific tested version here; it adds yet 
another thing to update for each release.  It seems better to establish a 
policy that glibc releases need to work with the most recent major GCC 
release as of when the first glibc release from that series was released, 
and then document that principle rather than specific versions (so 4.8 was 
most recent major release as of glibc 2.18, so all glibc 2.18.x releases 
should work with GCC 4.8.y and using the most recent 4.8.y is generally 
appropriate).  Something like "Releases of @theglibc{} are tested to build 
using the stable GCC release series current when the first @glibcadj{} 
release (@var{major}.@var{minor}) of a series 
(@var{major}.@var{minor}.@var{patchlevel}) is released.".
