This is a minimal resurrection of a handy, though bit-rotted, old tool.

Subsequent patches make it more palatable and likely to be maintained.
Stay tuned for more clean up before giving it a spin.  I've staged the
commits so successive versions can be built and tinkered with rather
than doing one massive re-write than cannot be easily factored out.

Fixed some compiler warnings:

Defer to "scheme.h" for deprecated `fast' and several other niceties.
Added missing `#include <stdlib.h>' (for `malloc()',`free()',`exit()').
Removed obsolete static `memory_base' global ("load.c" no longer uses).
Removed obsolete static `string_buffer[10]' global (no longer used).
Fixed `main()' return type to canonical `int' (and made it return so).
Initialized uninitialized `Next' ptr to `((SCHEME_OBJECT *) NULL)'.
Appeased `sscanf()' by passing constant strings, not string literals.
