OK, I found the problem.

# It is inconvenient to specify extra dependencies in custom build
# rule macros.  Much easier to do them separately here.
# Most generated .c files depend on non-generated .scm sources.

MACRO(C_SCM_DEPS outroot)
  # After outroot, you supply roots of additional scheme dependencies.
  # Put all optional arguments in deproots.
  SET(deproots ${ARGV})
  LIST(REMOVE_ITEM deproots 0)
  ADD_SUFFIX(deproots dep_scm .scm)
  ADD_PREFIX(dep_scm source_dep_scm ${Chicken_SOURCE_DIR}/)
#  ADD_FILE_DEPENDENCIES(${Chicken_BINARY_DIR}/${outroot}.c ${source_dep_scm})
ENDMACRO(C_SCM_DEPS)

ADD_FILE_DEPENDENCIES can not be used to add a depend from a source file to another
source file.  The macro basically, calls OBJECT_DEPENDS on the .c file.  It is meant
to add an extra depend onto a .o or .obj file, and should not have anything to do
with custom commands.   Any effect it has on them can not be expected to work.
If I comment out the above it works.   There may be some way to unify the
depend stuff a bit more, but for now (CMake 2.4.2 and less ) you will have
to use the DEPENDS on the custom comand.
