Hello ,

I'm trying to build* Tiny-curl-7.72.0 *on visual studio from source , I'm
facing this syntax errors on *system.h* and *multi.h*
i'm using following tags :

*#define HTTP_ONLY*
*#define BUILDING_LIBCURL*

tiny-curl-7.72.0\include\curl\system.h(566,16): error C2061: syntax error:

/*
 * Try to keep one section per platform, compiler and architecture, otherwise,

 *
 * curl_off_t
 * ----------
 *
 * For any given platform/compiler curl_off_t must be typedef'ed to a 64-bit
 * wide signed integral data type. The width of this data type must remain
 * constant and independent of any possible large file support settings.
 *
 * As an exception to the above, curl_off_t shall be typedef'ed to a 32-bit
 * wide signed integral data type if there is no 64-bit type.
 *
 * As a general rule, curl_off_t shall not be mapped to off_t. This rule shall
 * only be violated if off_t is the only 64-bit data type available and the
 * size of off_t is independent of large file support settings. Keep your
 * build on the safe side avoiding an off_t gating.  If you have a 64-bit
 * off_t then take for sure that another 64-bit data type exists, dig deeper
 * and you will find it.

  This is an "external" header file. Don't give away any internals here!

  GOALS

  o Enable a "pull" interface. The application that uses libcurl decides where
    and when to ask libcurl to get/send data.

  o Enable multiple simultaneous transfers in the same thread without making it
    complicated for the application.

  o Enable the application to select() on its own file descriptors and curl's
    file descriptors simultaneous easily.
