Ray-

Wow!  THANKS for taking the time for such a detailed explanation.  That
helped tremendously.

I downloaded curl-7.51.0.zip from https://curl.haxx.se/download.html and it
all worked beautifully.  And I did need

mingw32-make.exe mingw32 CFG=sspi-winssl

so thanks for your forethought in that.

I switched over to libcurl.a, and tried to add the CURL_STATICLIB compiler
flag, but the .exe still requires libcurl.dll - is that expected?

Compiler flags are:
