Wt

Compiling Wt 4.2.x with MinGW 9.2.1 64 bit on Windows 10 fails here:

D:\Dev\BuildLibs\wt\wt-4.2.1\src\http\Reply.C: In function 'void http::server::httpDateBuf(time_t, Wt::WStringStream&)':
D:\Dev\BuildLibs\wt\wt-4.2.1\src\http\Reply.C:74:3: error: 'gmtime_r' was not declared in this scope; did you mean 'gmtime_s'?

This issue can be fixed when commenting out #ifndef _MINGW32 and the corresponding #endif

in gmtime_r section of src/http/Reply.C

This code used to run using earlier MinGW versions and I'm not sure about the consequences of the above fix.

However, I did (painfully) learn about so many issues with MinGW versions <9 (std::any and non-deterministic random number generation leading to hash-token collisions) that it is not really advisible to use MinGW prior version 9 anymore.
