Message:
Oops, sorry. I had been a misunderstanding.
I can make WITH OUT --enable-werror option.

Thanks.

Message:
I can only repeat: there are a few compiler warnings and we're working on
fixing them.

If you want to compile curl successfully with the warnings present you
SHOULD NOT use configure's --enable-werror option.

You have two options: fix the warnings or remove the configure option. I
believe we have some modifications in git in that areas that have attempted
to remove the warnings.

Message:
So you used -Werror again and then you get error again?
