Dear Corinna,

> L is of type Long == int32_t, aadj is of type double.  The value of aadj at

2529648000 is a valid unsigned long, but not a valid signed long. The largest 
32 bit long is 2^31-1 = 2147483647. 0x96c75d80 interpreted as a signed long is 
a negative number.

I would say if floating point instructions are used to convert 2529648000 to a 
signed 32 bit integer, they should produce an FE_INVALID exception.
