someday didn't take too long :)  but it ain't pretty.

I installed all fedora packages under a directory and ran greg's tool over:

/sbin /usr/sbin /bin /usr/bin /usr/kerberos/bin/ /usr/kerberos/sbin/

Aggregate results:

   4070 29.1% are scripts (shell, perl, whatever)
   6598 47.2% don't use any stat() family calls at all
   1829 13.1% use 32-bit stat() family interfaces only
   1312  9.4% use 64-bit stat64() family interfaces only
    180  1.3% use both 32-bit and 64-bit stat() family interfaces

list of packages, sorted by the semi-lame "number of files in package
which call a 32-bit stat variant" metric:

I'm going to see if I can't leverage Fedora to clean some of this up.
