Lies, damn lies and end-of-block comments

I was reading reentr.h and noticed a lot of the endif's for the
HAS_XXX_R macros were wrongly indented and their comments had the
wrong condition.

The attached patch fixes the indentation and removes all but the last
comment which is shortest and furthest from its start.  No point in an
end-of-block comment on a one statement block, just falls out of date
and obscures the structure.

(plus "make regen")
