Version

wolfSSL Release 5.6.6

Description

Build fails on windows using msvc with some syntax errors when quic is enabled.
To fix it, I had to add #include <stdint.h> in quic.h for uint8_t
And define #define STDERR_FILENO 2 in api.c

Reproduction steps

mkdir build
cd build
cmake -DWOLFSSL_QUIC=yes ..
