CP2101 make bug

Hello, I download the beta version of cp2101 from ftp://ftp.silabs.com but when I try to compile the source code I got errors. For example:

mcci_usb.c:4106: error: ‘va_list’ undeclared (first use in these function) and some others errors…

I have two kernel version (2.4.29 and 2.6.12.2) and get the same bugs for both kernels.

What shall I do?

Are

Maybe try adding ```
#include <stdarg.h>
