In libldap/utf-8-conv.c:194

            if( wchar < 0x80000000 )

I get a warning about signed/unsigned comparison. What seems to happen is that wchar (which is of type wchar_t) is a signed integer (on my i386,it's a 4 byte int) and thus it's always < 0x80000000 by definition. ANSI C converts 0x80000000 to unsigned, thus the warning.

That code is only in use when sizeof(wchar_t) >= 4. The C library standard mandates wchar_t to be integer, thus signed. If I promote 0x80000000 to 0x80000000LL, when sizeof(wchar_t) == 4, like in my case, the test will always be true, and the compiler will complain about the test always being true. Everything would be fine otherwise.
