I have checked in a patch.  It does build under sh m2e, but when I 
attempt to use the sh-elf-run simulator to test m23, my test outputs 
gibberish.  I do not believe the simulator can handle code compiled and 
linked with m2e option as the same thing happens when I use the old 
strtod code.  It does work fine with the default compiler options.
