2515	Can't build QUIC binaries for windows	sonqor@…		"I have tried to build Nginx from sources for Windows using either [https://github.com/quictls/openssl.git 'quictls (openssl-OpenSSL_1_1_1u-quic1)'] or [https://github.com/openssl/openssl.git 'openssl (openssl-OpenSSL_1_1_1u)'] with '--with-http_v3_module' parameter. But the following fatal error will be occurred each time:

{{{

Stop.
}}}

But if I want to build nginx without '--with-http_v3_module' parameter, the building process will be successful:

I want to know what's wrong with the HTTP/3 QUIC module in windows? Especially in below paths:

**src/event/quic/ngx_event_quic_connection.h(109)
src/event/quic/ngx_event_quic.c(436)**

In other words, when QUIC will be supported on the Windows operating system? Because the official documentations in [https://nginx.org/en/docs/quic.html Nginx.org] has noted that QUIC is only available in Linux builds:
''Support for QUIC and HTTP/3 protocols is available since 1.25.0. Also, since 1.25.0, the QUIC and HTTP/3 support is available in Linux binary packages.''"	defect	closed	major	nginx-1.26	http/3	1.23.x	invalid	QUIC HTTP/3	sonqor@…	CL v19.36	"nginx version: nginx/1.25.1
