Robert P. J. DAY says:

apparently, the patchset for gcc 4.2.1 applies properly to the
source for gcc 4.2.2 and gcc 4.2.3. so, if you want, you can simply
add support for those last two just by augmenting menuconfig and
adding a couple symlinks for those two directories. seems like a
cheap way to add a couple new versions.

     9 Hi,
    10 
    11 The appended patch fixes a typo in a low-level lock function.  It
    12 set the correct 3rd argument for the futex syscall in loop.  Sorry
    13 for missing such an embarrassing bug.
