2.97 frystyk 17: This file makes up for the differencies in the systems and platforms supported
18: by libwww. On Unix, it is a question of <A HREF="../../INSTALL.html">using
19: autoconf</A> to figure out what environment we are in. This is done by running
20: the configure script which creates a <CODE>config.h</CODE> file. This
21: configuration include file contains a large set of macro definitions telling
22: what features we have and don't have. On platforms not supported by autoconf
23: (Windows, Mac, VMS etc.) you will find the information normally contained
24: in the <CODE>config.h</CODE> file directly included below. The
25: <A HREF="#Platform">second part of this file </A>uses all the information
26: that we either have from the config.h file or directly coded and actually
27: does the includes etc.

452: The last three do not interfere with the unix i/o library, and so they need
453: special calls to read, write and close sockets. In these cases the socket
454: number is a VMS channel number, so we make the @@@ HORRIBLE @@@ assumption
455: that a channel number will be greater than 10 but a unix file descriptor
456: less than 10. It works.
