Fix compilation on MinGW with -std=c99

commit 9223336a88bc moved the CFLAGS="-std=c99" bit in configure.ac
before the "socklen_t" test, which relies on #ifdef WIN32 to decide
whether to include <ws2tcpip.h> or <sys/socket.h> - which is no longer
defined then, and things explode in interesting ways.

Change to _WIN32, which is the "always defined on all compilers" define
for this.
