libcurl failure with --disable-netrc

[codesniffer13]

I did this

Built curl-7.65.3 from source and included (among other options) --disable-netrc. Tried to HTTP download from various public websites using the curl build (I ensured my PATH & LD_LIBRARY_PATH were setup to use only my build) but getting failures:

$ curl -o index2.html http://www.google.com
curl: (48) An unknown option was passed in to libcurl

curl -o index2.html https://www.google.com
curl: (48) An unknown option was passed in to libcurl

When I build with --enable-netrc then it works fine.

I expected the following

Successfully download webpages which do not require authentication.
