Well, I don't use cups.  As a good Unix citizen I have always used a
Postscript printer (or gs) and apsfilter.  However, I can see that it is
hard these days to make a life without cups.

I wonder why we need most of these development packages.  If they are
needed, it means that the Windows software is being build using header
files of the build system and not of the target (i.e. Windows).  This is
error prone because it assumes that the header files are identical.

To solve this problem we need to check that the build system's header
files are never picked up when building for Windows.  I am not sure how
this can be done.  The GnuPG related foo-config scripts and M4 macros
compare the version and issue a warning but most other software does
not.  Eventually we need to write a sanity checker to detect such
possible flaws.

For some libraries tools are required to run on the build machine during
the build for Windows.  This is the reason for some of the -dev package.
A saner approach would be to build the library first for the build
platform and only then for the target.  Uhh, quite some work.

Using a dedicated virtual machine for building might be a good idea.
This would also solve the problems for Fedora or Suse users.
