On closer inspection, the socket dependency is limited to the socket
error codes in <system_error>, such as ECONNRESET et al. One less
problem. I am initially aiming for a non-math-correct version of libc++
that builds and can replace everyday STL headers, such as <vector>,
Is this WinC99 lib being worked on by anyone? Never heard of it except
for the wiki entry...
