In case this is a question (sorry, I tend to always believe everybody else surly
knows the problems and reasons for a long time before I do):
There are two unrelated problems, first is that version.sh is completely broken
for a long time and touches version.h after every svn up (no matter if something
was updated or not). Patch pending.
The second, probably more difficult problem is that every touch of version.h not
only forces a rebuild of mpcommon.o, but compiles (nearly?) everything. The
simple solution would be to teach Makefile exactly the dependencies version.h is
needed for (the files in this patch plus muxer_avi.c and something like
win32/gui.c)). I thought it would make more sense to reduce this number using a
global variable VERSION and then change Makefile to know mpcommon.o depends on
version.h.

Please advice, Carl Eugen
