That makes no sense.  There must be something different about how you're
using libcurl vs. curl.  Have you tried curl's "--libcurl <file>"
option?  I would try that.  Basically, take the curl command line that
works, and then add the "--libcurl <file>" option to it, and it will
emit C source code for a program using libcurl that does the same thing.
Compare that with how you're using libcurl.
