Is that "#include <netinet/in.h>" required in ip6.h at all? It also seems
to compile if I omit that include completely here...

Anyway, I just tried with my mingw32 cross-compiler, and once this is fixed,
compilation succeeds, but there are some warnings:

net/slirp.c: In function 'net_slirp_init':
net/slirp.c:249:5: warning: implicit declaration of function 'inet_pton' [-Wimplicit-function-declaration]
     if (!inet_pton(AF_INET6, vprefix6, &ip6_prefix)) {
     ^
slirp/ip6_icmp.c: In function 'icmp6_send_error':
slirp/ip6_icmp.c:84:5: warning: implicit declaration of function 'inet_ntop' [-Wimplicit-function-declaration]
     inet_ntop(AF_INET6, &rip->ip_dst, addrstr, INET6_ADDRSTRLEN);
     ^
qemu/slirp/ndp_table.c: In function 'ndp_table_add':
qemu/slirp/ndp_table.c:16:5: warning: implicit declaration of function 'inet_ntop' [-Wimplicit-function-declaration]
     inet_ntop(AF_INET6, &(ip_addr), addrstr, INET6_ADDRSTRLEN);

The warnings go away when I use this piece of code in the beginning of the affected files:

#ifdef _WIN32
#define _WIN32_WINNT _WIN32_WINNT_WIN6 
#include <ws2tcpip.h>
#endif
