Avoid signed/unsigned comparison
Some compilers implicitly cast the result of uint_fast16_t *
uint_fast16_t to something signed and then complain about the
comparison to (unsigned) size_t.
Casting phnum to size_t is a good idea anyway as 16bit multiplication
can easily overflow and we are not checking for this.
