I am building Pound 2.4.4 on CentOS 4, and am getting this compiler warning:

This is directly out of the box, no changes on my part.

warning: this decimal constant is unsigned only in ISO C90 - is not a
problem, as it is used only as a bit mask. The warning is harmless, but
I know of no portable way of avoiding it (gcc is easy, but consider
other compilers as well).

warning: assignment from incompatible pointer type - is a harmless
casting error. We'll take care of that in the next release.[...]
