Only with gb_CHECKOBJECTOWNER=T otherwise its down to 10 seconds in tail_build,
which is likely mostly stat'ing.

Anyway: I implemented a "make countoutdated" proof-of-concept:

http://cgit.freedesktop.org/libreoffice/core/commit/?id=05a33692a084f59f2fae0a535131133d2a3f6b72
http://cgit.freedesktop.org/libreoffice/core/commit/?id=8ee4e99a78a7a7f16bafa56e08ef9649cc69dbdb

which does not add much complexity to the existing build system by being an extension.
Now you can do:

 make countoutdated
 make countoutdated check
 make countoutdated build

to quickly check etc. how many files would get rebuild in workdir right now. Of
course, that _could_ be easily used to create some progress counters, if one
doesnt mind the ten extra seconds.

For example it shows that touching sw/inc/doc.hxx causes:

 $ make countoutdated -W `readlink -f sw/inc/doc.hxx`
 CxxObject: 393
 Module: 39
 LinkTarget: 9
 RdbTarget: 8
 CppunitTest: 9

to be rebuild. It also shows there is still something very wrong about generated headers in oox.

Best,

Bjoern
