IMHO #3 sucks more, it's not as easy to spot when glossing over the
code, the underscores make it quite ugly (think _r________) and it's
less "greppable". If I know that there's something that sets S_ISUID, I
can easily search for that, compare that to [_cpdbl]{1}[r_]{1}[w_]{1}s...
I agree with Steinbink. But how about having macros like,
S_I0700, S_I0070, S_I6444 ..etc. They combine visual appeal of octals,
easy to grep, easy to decipher ...etc.
