Functions in `wolfio.c` unconditionally reference SOCKET_* error codes, even if `errno.h` is conditionally includes in wolfio.h. When compiled with at least WOLFSSL_NO_SOCK + WOLFSSO_USER_IO `wolfio.h` decides not to include `errno.h` and therefore SOCKET_* symbols are missing. Instead of changing "decision tree" in `wolfio.h` and risking breaking it on platforms I couldn't test, use "last resort" include of 'errno.h' in the wolfio.c if configure process detected its presence.

Hi @redbaron, Thank you for this PR. I do not see you are an approved contributor. For such a small change we will likely treat as a bug report, attempt to reproduce and fix ourselves. Can you tell us more about your project? Thanks, David Garske, wolfSSL |
