forked from Imagelibrary/rtems
<valette@crf.canon.fr> to add a port of the GoAhead web server (httpd) to the RTEMS build tree. They have successfully used this BSP on i386/pc386 and PowerPC/mcp750. Mark and Joel spoke with Nick Berliner <nickb@goahead.com> on 26 Oct 1999 about this port and got verbal approval to include it in RTEMS distributions.
