gcc-20001027: Funny handling of sizeof()

[Horst von Brand]

Linux, Red Hat 7, i686

The line below (distilled from a macro for computing alignment) gets the
anoying and useless warning:

/tmp/tst.c:1: warning: large integer implicitly truncated to unsigned type

This warning disappears if sizeof(long) (a constant) is replaced by 4 (the
same constant!), or if the result is used to initialize an unsigned int.

int i = (5 + 4 - 1) & ~(sizeof(long)-1);
