I'm running chicken from the experimental branch on OpenBSD 4.8.

I'm using the time-related routines in srfi-18.

The following program:

$ csi
#;1> (use srfi-18)
; loading library srfi-18 ...
#;2> (time->seconds (seconds->time 2))
2000000.0

I would expect the output of the conversion to be symmetrical, where if I give (seconds->time) a 2, converting the time back to seconds using (time->seconds) should return 2. (probably 2.0) Instead this call is returning the microseconds.

I would love to see srfi-18 extended to have a (time->microseconds) and (microseconds->time) procedures, as I love having time resolution at this scale. This could also, of course, be fixed by scaling the real number returned from these routines.

I'm not sure this issue can be fixed, but here it goes:

The following code:

(define (foo)
  (if condition (for-each (lambda x x) '(0 1 2))))

when compiled with '-picky', gives the following warning:

Warning: in toplevel procedure `foo':
  conditional in tail-position has branch with undefined result:

(if condition (let (... ...) (let ... ...)) (##core#undefined))

However, the other branch *also* returns an undefined result, making this particular warning a no-op in this case.

I would expect to not see this error when both branches return the same result.

Is this condition detectable?

I'm running Chicken from the experimental branch. After updating to 806bdb60d143712646a07ae891101a11a1511ab6, I try to install the genturfa'i egg and I get the following error:

/opt/chicken-master/bin/csi:/opt/chicken-master/lib/chicken/5/genturfahi.so: undefined symbol 'C_srfi_2d1_toplevel' lazy binding failed! Segmentation fault (core dumped)

This is the genturfah'i egg r22075.

Do I need to add or remove an srfi declaration? I'm not sure what behavior in Chicken changed and whether I'm seeing a bug introduced in Chicken or whether a fix in Chicken introduced a bug in my code.
