The regex changes look fine, but it would be best to add the copy
constructor instead of allocating it on the heap.

+#ifdef _WIN32
                 bytes_sent = ::sendto (m_fd_send,
+                                       (char*)src,
+                                       src_len,
+                                       0,
+                                       m_udp_send_sockaddr,
+                                       m_udp_send_sockaddr.GetLength());

Here we could maybe keep the cast, I think it would work even in non-MS
platforms (where it's void*), and avoid duplicating the code for both

+//#include <ar.h>

Here maybe we should just ifdef it and add the missing declarations on
Win32? Either that or just remove the include and just use our own

+        abort();

I don't really like the use of abort on to be used as libraries, so maybe
an assert / llvm_unreachable? Also why is this added here? Is this code
expected to never run under non-Apple OS?

+#ifdef _WIN32
+ WSADATA dummy;
+ WSAStartup(0x202, &dummy);

This should probably be added elsewhere on the LLDB initialization path on
Windows if other plugins use the socket functionality, else we'll need to
duplicate this in every plugin initialization path.

+#ifdef _WIN32
+ Sleep (100);
+ usleep (100000);

We should add an abstracted function for this as sleeping seems to be used
on a couple places.

The rest of changes look fine to me.
