$ make makeobj_prog
make[1]: Entering directory `/home/space/factory/simutrans-svn/src/simutrans-build/trunk/makeobj'

(I have snipped the output to just contain the error.)
If more information is required, please let me know thanks.

Note: SVN 4813 now compiles building_writer.cc

I get the same error with gcc 4.5.2 on Windows.
