I did this

Defined both CURL_DISABLE_CRYPTO_AUTH and USE_SSL.

I expected the following

A successful compilation. Instead I get the following errors:

1>vtls\vtls.c(1065): error C2065: 'MD5_context' : undeclared identifier
1>vtls\vtls.c(1065): error C2065: 'MD5pw' : undeclared identifier
1>vtls\vtls.c(1069): error C2065: 'MD5pw' : undeclared identifier
1>vtls\vtls.c(1069): error C2065: 'Curl_DIGEST_MD5' : undeclared identifier
1>vtls\vtls.c(1070): error C2065: 'MD5pw' : undeclared identifier
1>vtls\vtls.c(1072): error C2065: 'MD5pw' : undeclared identifier
1>vtls\vtls.c(1073): error C2065: 'MD5pw' : undeclared identifier

curl/libcurl version

7.56.0

operating system

Windows, Visual Studio 2017.

A solution (but maybe not the best solution)

In vtls.c add #ifndef CURL_DISABLE_CRYPTO_AUTH around the Curl_none_md5sum function. Then set Curl_ssl_multi md5sum parameter to NULL (instead of Curl_none_md5sum). Do the same for Curl_ssl_schannel md5sum parameter.

I am also seeing this when compiling for android, iOS, or macOS.
