RE: cgicc + FastCGI, patch

[Stephen F. Booth]

I haven't had a chance to look at your patch yet, but I actually did make
changes to cgicc to make it compatible with FastCGI.  But, I updated the
website before releasing the next version.  So, unless you're using the CVS
version of cgicc, the FastCGI changes aren't in there.  Basically what I did
was add a new constructor for the Cgicc class that takes a reader_function_t
to use for writing the output.  I've typedef'd reader_function_t to

//! A stream-reader function, for FastCGI compatibility
typedef size_t (* reader_function_t)(void *, size_t);

in CgiEnvironment.h

I'll look at your patch and see if you did things similarly or better.  In
any case, sorry for the confusion.  I updated the website quite a while ago,
then started doing massive changes to the library and never 'undid' the
changes to the website when I didn't release the new version.
