This workaround will not work in two cases, and is the reason behind
pushing ebx on the stack (otherwise the values would have been passed
using "ebx" and not "m") and restoring it later: in PIC code (shared
libraries), and under BeOS, the ebx register is not allowed to be

It is necessary because p_u and p_v are modified in memory from the
