Um, yes it does.  Maybe wou don't have your warnings set high enough.  That
particular construct will generate a "variable initialised but never used"
warning.

Re-read your compiler switches manual, especially the warning stuff.

Our programmers all get really annoyed when they run a big compile, only to
have it bitch at the last minute that "this variable was not used" - because
we have warnings treated as errors, so it stops the whole shebang, rather
than being an ignored warning.
