you should convert the program to use strerror()
ok I'll work on it
strerror() and SYS_ERRLIST[] are interchangeable, so shouldnt be too much work ;) i would suggest sending the patch upstream and apply this for all setups (not just uclibc) ... SYS_ERRLIST is the old style method of getting error strings
done. You can find the patch here: http://dev.gentoo.org/~xmerlin/ppp-sys_error_to_strerror.patch I'll file a bug to request the integration in the ppp ebuild, and I'll ask to integrate it upstream.
