If PHP is built without complete ANSI C prototypes in scope the 'round'
function can fail.
This is because the second argument to 'pow' in ext/standard/math.c:143
is an integer, and without prototypes it doesn't receive its implicit
cast to a double, causing the 'pow' function to receive an undefined
value on the stack.
The simple fix is to put an explicit (double) cast in:
f = pow(10.0, (double)places);
A better fix might be to ensure that the ANSI version of the prototypes
from <math.h> are always in scope, but that may be difficult to achieve
across a wide variety of systems.
