apr_socklen_t seems to work all around (tested on Sol 2.6, RHL7.1, FreeBSD
4.3, visually inspected on msdn for win32).

But you know what?  I'm an idiot and just plain can't count... it was
never the len parameter that was giving me trouble on Solaris 2.6 in the
first place... it was the error parameter, which is currently an int
getting passed in as an int* (assuming the function expects void*).  For
some funky ass reason, Solaris 2.6 ifndef _XPG4_2 (and apparently Win32 as
well, if msdn.microsoft.com is correct) expect it to be a char*!
Obviously, you can't convert an int* to a char* without a cast, so the
warning is perfectly valid.  Casting it to (char *), while ugly, seems to
fix the problem on all the platforms I can test.  If there's any platform
out there that expects something other than char* or void*, they can just
deal.  =-)
