Lots of warnings with gcc4 on Fedora

[Joost Soeterbroek <joost soeterbroek com>]

Hi,

I am compiling (clearsilver) on Fedora4 and I am seeing a lot of these
warnings:

html.c:721: warning: pointer targets in passing argument 1 of 'strlen'
differ in signedness
html.c:721: warning: pointer targets in passing argument 1 of
'__builtin_strcmp' differ in signedness

Are these safe to ignore?

gcc version 4.0.1 20050727 (Red Hat 4.0.1-5)

Regards,

Joost
