There is a special case in nabstime.h for AIX, which imho
got swapped. The normal case for me would be INT_MIN
and not the 0x80000001.
There is a comment that I don't understand at all given the below 
source code:

/*
 * AIX considers 2147483648 == -2147483648 (since they have the same bit
 * representation) but uses a different sign sense in a comparison to
 * these integer constants depending on whether the constant is signed
 * or not!
 */
#if defined (_AIX)
#define NOSTART_ABSTIME ((AbsoluteTime) INT_MIN)
#else 
#define NOSTART_ABSTIME ((AbsoluteTime) 0x80000001)             /* -2147483647 (- 
2^31) */
#endif

But that is unfortunately not the problem. Looks like yet another broken compiler to 
me :-(
