That's fine, if you prefer:
ptimer.c:95:46: operator '' has no right operand
This doc makes it appear that the unistd.h here does not conform:

I suppose we should then use:
#ifdef _POSIX_TIMERS
# if _POSIX_TIMERS 0
... use POSIX timers ...

The usual solution to this problem is:
#if _POSIX_TIMERS - 0 0
That gets the right answer regardless of whether _POSIX_TIMERS is
undefined, defined as nothing, or defined as a number.

#ifdef _POSIX_TIMERS
# if _POSIX_TIMERS 0
Doesn't help. It's defined, but null.
Mr, Jones is probably close to the right answer with:
#if _POSIX_TIMERS - 0 0
I was looking for a way to make null look like positive, but a little
more reading

Neat trick, thanks.

I guess the defined as nothing case was losing. BTW does the above
trick work with KR preprocessors?
Yep. (That's why it uses - 0 rather than + 0, the latter is only
valid for ANSI C.)
