maybe 0x80000000 gets interpreted as unsigned and then the compiler
complains. E.g. in machine/limits.h you find

#define INT_MIN         (-0x7fffffff - 1)       /* min value for an int */   

(to tell the truth you also find there the following definition
for UINT_MAX, and I don't understand why the 'U' is necessary then)

#define UINT_MAX        0xffffffffU     /* max value for an unsigned int */
