And it's a lot of work too. (thanks Randy)

It could be something like:

$ grep-2.5.4 -nrP --include=*.[ch] '\b([A-Z]?[a-z]{2,}\b)[ \t]*(?:\n[ \t]*\*[ \t]*|)\1\b' * | \
  grep -vP '\b(?:struct|enum|union)\s+([A-Z]?[a-z]{2,})\s+\*?\s*\1\b' | \
  grep -vP '\blong\s+long\b' | \
  grep -vP '\b([A-Z]?[a-z]{2,})(?:\t+| {2,})\1\b'
