I just tried to compile package xorg-x11-doc-7.2-14
with the new GNU compiler version 4.3 snapshot 20070126

The compiler said

imLcPrs.c:600: warning: array subscript is above array bounds

The source code is

    if (l == LOCAL_UTF8_BUFSIZE - 1) {
        local_wc_buf[l] = '\0';

but

	wchar_t local_wc_buf[LOCAL_WC_BUFSIZE]

#define LOCAL_WC_BUFSIZE 128
#define LOCAL_UTF8_BUFSIZE 256

so the program is trying to index 255 into an array of size 128.

Suggest code rework.
