Re: [Mingw-w64-public] Determine whether a mingw-w64 port of gcc is UCRT or MSVCRT

Given that I have, in my path, a mingw-w64 port of version 13.2.0 of
gcc.exe, is there a gcc command that I can run to determine whether this
gcc uses UCRT ?

I thought that running "gcc --version" would do that - and it does for
Brecht Sanders builds ... but niXman's UCRT and MSVCRT builds both report
the same for "gcc --version".

Is there instead something in "gcc -v" that I should be looking for ?



```
echo '#include ' | x86_64-w64-mingw32-gcc -E -dM -xc - | fgrep _UCRT
```

gives `#define _UCRT` if the headers have been configured to use UCRT by 
default.
