I was writing the trace function, which is included by Whippet, which doesn't have the BUILDING_LIBGUILE define. It is just as fine to put these in private headers; better, even. * libguile/frames-internal.h: * libguile/values-internal.h: New files. * libguile/Makefile.am (noinst_HEADERS): Add new files. * libguile/backtrace.c: * libguile/continuations.c: * libguile/control.c: * libguile/eval.c: * libguile/frames.c: * libguile/frames.h: * libguile/gsubr.c: * libguile/init.c: * libguile/intrinsics.c: * libguile/numbers.c: * libguile/print.c: * libguile/smob.c: * libguile/smob.h: * libguile/stacks.c: * libguile/stacks.h: * libguile/values.c: * libguile/values.h: * libguile/vm.c: Include new files.
