[Bug c/33292] optimizer optimizes out a piece of code

[nicolas at dyalog dot com]

------- Comment #2 from nicolas at dyalog dot com  2007-09-03 14:07 -------
after a bit more work it seems optimized out because diff64() doesn't observe
strict aliasing... 
that was tricky because it was not the diff64() code that was snipped out but
TimeValToFileTime()...
I think the compiler should either warn (strict aliasing) in diff64, or not
remove TimeValToFileTime()...
Or did I miss something ?
