Description:
------------
Hi,

Multiple reports here:


/ext/standard/pack.c:
749                                                while (--len >= 0) {

len is unsigned, so it can never be <0




In /ext/dba/libflatfile/flatfile.c:

183                if (num < 0) {
num is unsigned
277                if (num < 0)  {
num is unsigned
129                if (num < 0)  {
num is unsigned
229                if (num < 0) {
num is unsigned



Thanks,


T

Yes, that fixed the pack.c one, but not the flatfile.c one.
