That "fixes" it...
The patch I attached does that and marks it with a big fat warning, since I 
think one should not rely on such hidden triggers.

More warnings are created by inclusion of my system (well, devpkg) headers 
being included before physfs' own ones. 
(I.e. "-I/home/devpkg/devpkg/include ... -I/home/devpkg/src/physfs-svn/." 
results in devpkg/include/physfs.h being included before physfs-svn/physfs.h)

If it is somehow possible, I'd appreciate if the CMake supplied CFLAGS could 
be moved after the custom ones. (This worked with automake somehow.)
If this is a CMake problem, I'll report it there instead...
