Conversion from negative float to unsigned int

[Fred Tydeman]

What is the result of assigning the negative floating point value (-1.0)
to unsigned char, unsigned short, unsigned int, and unsigned long?
 
Is the result 0, +1, the value with all bits on (UCHAR_MAX, USHRT_MAX,
UINT_MAX, and ULONG_MAX), or something else?
 
ANSI C 3.2.1.3 Floating and Integral and footnote 29 on page 36 are not
very clear.
