It fail, and I am not sure if it intended:

Can you test it with #15564?

[talregev]

Can you test it with #15564?

I rebase over your branch.

[talregev]

It solve the 'strtok_r': macro redefinition But there is more compilation problems.

[vszakats]

There is something funny going on when trying and failing to detect GSS_C_NT_HOSTBASED_SERVICE.
Failing to detect it may cause the 'gss_OID' differs in levels of indirection from 'int' errors.

Can you also apply #15545? It may help avoiding some warnings, and perhaps this, and perhaps-perhaps the detection above:

LINK : fatal error LNK1104: cannot open file 'gssapi64.lib'

https://github.com/curl/curl/actions/runs/11819947642/job/32931130624?pr=15549#step:7:690

This still leaves a bunch of other issues though.

[talregev]

I rebease over your other branch. It solve many problems.

[vszakats]

It fixed the detection and some of the warnings with it.

Reduced to this now:

D:\a\curl\curl\lib\krb5.c(652,28): warning C4244: 'function': conversion from 'curl_socket_t' to 'int', possible loss of data
D:\a\curl\curl\lib\krb5.c(654,28): warning C4244: 'function': conversion from 'curl_socket_t' to 'int', possible loss of data

D:\a\curl\curl\lib\krb5.c(666,24): warning C4244: 'function': conversion from 'curl_socket_t' to 'int', possible loss of data 

I don't understand which type is wrong. There is a sockindex (int) and
the socket itself (curl_socket_t). On Windows their types are not
interchangeable.

socket_write() is passed a socket, but expects a sockindex. Then
it passes down this sockindex to Curl_conn_send().

@talregev Would you mind opening an issue with the int/socket confusion warnings? To give it visibility.

I open an issue:
#15582

[talregev]

I disable warning as errors to see what happen next.

Thanks @talregev! I merged this separately and pushed in batch together with last round of fixes.
