Some general guidelines for modying this code:
* Use `scheme_...` for a definition that is globally visible. In
particular, any non-`static` function name should start with
`scheme_`.
* If a globally visible function is meant for exporting to embedding
applications, extensions, or through the FFI, put the prototype in
"src/schemef.h" (and re-generated files with `make exports`).
Functions available only to embedding applications can go in
"scheme.h". Otherwise, put global function prototypes in
"schpriv.h".
* Don't use "//" comments, because we still use pre-C99 compilers
that don't support them.
* Declare all variables at the beginning of a block (again, for
pre-C99 compilers).
