Re: In the Works: New OOo C++ Coding Standards

External header guards is not really the problem with makedepend. The
problem is that makedepend's running time is O(n^2) with n being the
number of source files in OOo. This is -after- the fixes, previously
it was more like O(n^3). Fixing this to run in O(n) means either
adding a new dependency type to dmake or using jam instead..

The external include guards are barely some smaller constant factor
for the O(n^2), if even that .. So IMHO we can happily ignore
makedepend in terms of deciding to strip out the external guards ..
