I'm leaning against the idea, since it hurts performance very slightly and does 
not fix any bugs (it's just a style thing).

The C standard explicitly says this is OK.  Obviously a compiler can warn about 
it anyway, but normally we just use the latest stable GCC and pacify it with the 
settings in $(GCC_DEBUG_FLAGS).  We don't have the time or inclination to pacify 
every pedantic compiler.  On a case-by-case basis we can fix some issues (as I 
just did with 'const') but in the case of this 3-char literal pacifying the 
compiler would bloat the executable, and it's not worth it.

Please don't forget to compile with -Dlint when you do that.
