I assume this is "warnings are treated as errors".

MSVC appears to think cmeth_lib.c is Unicode rather than ASCII.

(Yes, ASCII is a proper subset of UTF-8 and UTF-7. I mean MSVC appears to be complaining that it wants to see a UTF-16 BOM at the beginning of the file.)

And it seems to think that the lines in the file end with a bare CR, rather than a Windows CRLF or a UNIX LF.

And it seems to be finding a bunch of invalid code points.

I suspect the source file is corrupt. Have you looked at it? Did you check the signature on the OpenSSL tarball?

It's also possible that MSVC assumes UTF-16 source files under some conditions, possibly based on the Windows language settings. If that's the case, there ought to be some way to turn that off. Alternatively, you could transcode all the files from ASCII to UTF-16; that ought to be simple to script.

Or I could be way off and the problem is something else entirely.
