Description:
------------
Warnings while compiling xml.c with 4.3.3 as well as
php4-STABLE-200311020830:
ext/xml/xml.c: In function `xml_utf8_encode':
ext/xml/xml.c:489: warning: comparison is always true due to limited
range of data type
ext/xml/xml.c:493: warning: comparison is always true due to limited
range of data type
Relevant lines in xml.c are:
0455: static XML_Char *xml_utf8_encode(const char *s, int len, int
*newlen, const XML_Char *encoding)
0459: unsigned short c;
0484: if (c < 0x80) {
0486: } else if (c < 0x800) {
0489: } else if (c < 0x10000) {
0493: } else if (c < 0x200000) {
On Darwin, a short seems to be a 32 bit value; comparisons at lines
0489 and 0493 are thus, indeed, always true.
Now, function xml_utf8_encode seems to be used only for implementing
utf8_encode(), thus for encoding iso-8559-1 into UTF-8.
So, one could be tempted to consider those warnings as "don't care"
ones.
On the other hand, it seems that those warnings could be easily avoided
and thus allow for easier code maintenance.
HTH,
Axel
