Collision happens when building with mingw-w64 v3 or v2 while targeting
Vista or newer. `iphlpapi.h` includes `windns.h` in this case, which
defines macros named `DNS_TYPE_*`, colliding with curl doh enums.
The issue was fixed in mingw-w64 v4:

Fixes:
```
lib/doh.h:54:3: error: expected identifier before numeric constant
DNS_TYPE_A = 1,

This workaround seems harmless and generally good practice, but
another option is to require mingw-w64 v4.
Ref: #18009Closes#18041
If the long option name ends with an equals sign (`=`), the argument is
the text following on its right side.
This makes the command line parser accept this common style in addition
to the existing way to accept option arguments more similar to how other
command line tools do.
Example: `curl --user-agent=curl-2000 https://example.com/`
Change a few existing tests to use this syntax: 206, 1333, 1335, 1442
Closes#17789
This still allows users to explictily ask for 1.0 or 1.1 as the minimum
version. If the TLS library allows it.
Starting with this change, the CURL_SSLVERSION_DEFAULT value is no
longer used as minimum version when the TLS backend are called.
This also makes curl set the minimum version to 1.2 independently of
libcurl for the rare case where a newer curl tool would use an older
libcurl.
