For all practical purposes the semicolon count is good enough.  The only
"except for" I've ever thought made sense is not counting the semicolons
on the end of pragmas, but by actual count that is usualy less then 1% of the 
total.  If your generating SLOC number to be fead into cost-estimation tools
using any value with in the nearest 100 sloc is usually good enough.

This is highly compiler and CPU archetecture dependent and sould be determined
on a case by case basis by measurement of actual code.
