Perl is your friend. Perl has been ported almost everywhere. You shall not 
fear Perl :)

More seriously, Perl is not required here: this special header file listing 
the most dependent VTK header files could be generated from time to time 
manually or by a cron job and put/updated in the CVS.

I guess I should checkout a VTK tree and create a Perl script to add the 
following code to the beginning of each .cxx file (yes, it *has* to be at 
the beginning of a *cxx* file, before all other #include). Then compile the 
tree and check the compilation time. Then play with it a week or a month to 
see how it behaves...

#ifdef USE_PCH
#  ifdef _MSC_VER
#    include "vtksbPrecompiledHeaders.h"
#    pragma hdrstop
#  endif
#endif

(of course the name of the file can be changed, it was chosen to comply 
with my vtksb lib).
