I build things on linux so I have downloaded this via RPM.  I did a google
search and found several references to db2html.

Maybe someone will post a definitive source.  You don't need to build the
documentation, though.  The makefile will skip this step if it can't build
the docs.

There is a certain amount of setup available but I really don't advocate
using the cygwin sources from setup.exe for building anything.  The
sources change rapidly in CVS so you probably will be automatically out
of date if you use the sources for cygwin 1.3.2.

If you can't use cvs, then the snapshot sources should be adequate.  If
you extract the cygwin-src-yyymmdd.tar.bz2 file you should be able to
build.

Other individual packages may be buildable with some tweaking.

I am not sure how useful it is to be able to build the entire cygwin
release from scratch.  That sort of goes counter to the new philsophy of
updating individual packages on the fly.  I can't see why anyone would
want to build perl and postgres together.  I think the chances of
accomplishing this are low.

Although, now that I've said that, I will point out that I have a
/netrel/src directory that looks like this:

binutils-20010425-2  config.sub      cygwin-1.3.1-1      gcc-2.95.2-9    inetutils-1.3.2   mpw-install     tcltk
bison-1.28-1         configure       cygwin-1.3.2-1      gcc-2.95.3-6    install-sh        ocygwin-1.1.4   tcltk-20010307-1

config.if            cygwin-1.1.8-2  flex-2.5.4-1        include.gcc     mkinstalldirs     tar-1.13.19-1   zsh-4.1.0-dev-0

I also have a 'mknetrel' program that allows you to say:

mknetrel flex

to build flex-2.54-1.

I plan on checking this into a cygwin-apps repository on sources.redhat.com
soon.

This is not a generic "build everything from one makefile" solution but
it does provide a measure of consistency in building packages.
