Re: (ITS#8383) msys build error "portable.h:1116:19: error: two or more data types in declaration specifiers"

[ryan@nardis.ca]

I've run into this myself while trying to test ITS#9069 on Windows.

In my MinGW environment, <sys/socket.h> does not define socklen_t, so 
portable.h:1116 does '#define socklen_t int'. However, <ac/socket.h> 
includes <ws2tcpip.h> which does typedef socklen_t.

base64.c includes "portable.h" first and then <ac/socket.h> later. This 
second include triggers the error as the original typedef essentially 
becomes "typedef int int".

I think we can fix it by searching the Windows header as well, avoiding 
the #define appearing in "portable.h".
