    The http.int file is an intermediate file that is created during
compilation. From that intermediate file the http.obj file is created.

    The *big* number in the error mesage is the Line Number within the
intermediate file where the error is noted.

    In the particular cae above, the C structure POLLFD is doublt-defined,
first in Borlands's winsock2.h, *then* inside the Curl's select.h file.

    Yes, you are certainly correct: a double include !!!

    As I noted in my first email: commenting out the pollfd struct in
select.h reveals a *later* undefined symbol (wcsdup) in the file easy.c :((

Thanks for the response, and hope I can be of more help de-bugging this
problem
