#3018 strncpyz error on long parameter name

[Gabriel Ravier]

int f(int aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa)
{
}

Compiled with sdcc test.c, this gives strncpyz prevented buffer overrun!. Tested with commit 11647.

I cannot reproduce this using SDCC built from current trunk on my Debian GNU/Linux testing system.
