SRS for Windows

SRS 5.0.89+ supports Windows(Cygwin64).

SRS 7.0.60+ remove the supports for Windows, because it's too complex to maintain.

Please use WSL(Windows Subsystem for Linux) which starts a Ubuntu in Windows, so you can simply build and run SRS by:

wsl --install -d Ubuntu-22.04

Winlin 2022.11
