A.D.F. -> httpd -> thttpd -> patches -> thttpd-2.20c

1. Features

The following patches apply to original thttpd-2.20c and enhance (a bit) its performance;  they also fix a few small / rare bugs.  Latest patch includes:

• compile-patch, should allow latest ANSI C/C++ compilers to compile thttpd without fatal errors;

• fast-close-patch, allows a faster close of socket connections when using a lingering close;

• block-mode-patch, fixes no-block -> block -> no-block mode switch to avoid possible hangs when lingering on a socket close;

• other minor bug fixes.
