What gives?? Is there an environment variable that can be set to force gcc to not attempt to use this option (in the configure logs, it discovers that "-Wno-overlength-strings" is not an available option.? WTF?

We've run into this several times with 4.3.  Never did find a solution and
ended up going away with 4.4.

Comment 13 (which i sadly just noticed now): 
Since this is the "make install" stage, there shouldn't be any recompilation
necessary, but in my log file, it shows that "Must remake target
`cc1-checksum.o'", which caused the compile error mentioned in the opening. The
interesting bit is that inside the work/build/gcc dir there is a
"cc1-checksum.c" file, but no .o nor executable was created for it (but
cc1plus-checksum.o does exist).
