What would you think about an autoconf-like approach generating a 
"package-VER.sh" script from some "package.sh.in" (yes, no version).

Then fixes and new features will be added to only one generation tool 
(autogbs ?-)) which can be part of a standard Cygwin package managed by 
setup.exe.
The generator can check the actual structure of the source tree to 
create a smaller build-script.

New features can be opt'ed in by directives in the package.sh.in script 
if desired.
Like with autoconf, it would be possibled to do special hacks by 
including shell code verbatim.

The package-sh.in can be put in the CVS of maintainer or be part of 
projects sourcecode (e.g. as some Cygwin-build-script.sh.in)
