 Mac OS. Windows supports TCP Fast Open starting with Windows 10, version 1607

 and we should add support for it.

1.25 Remove the generated include file

 When curl and libcurl are built, one of the public include files are

 generated and is populated with a set of defines that are derevid from sizes

 and constants for the particular target architecture that build is made. For

 platforms that can select between 32 bit and 64 bit at build time, this

 approach makes the libcurl build only create a set of public headers suitable

 for one of the architectures and not both. If you build libcurl for such a

 platform and you want to allow applications to get built using either 32/64

 version, you must generate the libcurl headers once for each setup and you

 must then add a replacement curl header that would itself select the correct

 32 or 64 bit specific header as necessary.

 Your curl/curl.h alternative could then look like (replace with suitable CPP

 variable to check):

     #ifdef ARCH_32bit

     #include <curl32/curl.h>

     #else /* ARCH_64bit  */

     #include <curl64/curl.h>

     #endif

 A fix would either (A) fix the 32/64 setup automatically or even better (B)

 work away the architecture specific defines from the headers so that they can

 be used for all architectures independently of what libcurl was built for.
