/*
 * stubs for C-linkage library functions which we need to refer to 
 * from Lisp 
 *
 * (But note this is only the Linux version, as per the FIXME
 * note in the BSD version in undefineds.h.)
 *
 * These stubs exist for the benefit of Lisp code that needs to refer 
 * to foreign symbols when dlsym() is not available (i.e. when dumping
 * cold-sbcl.core, when we may be running in a host that's not SBCL,
 * or on platforms that don't have it at all). If the runtime is
 * dynamically linked, library functions won't be linked into it, so
 * the map file won't show them. So, we need a bunch of stubs that
 * nm(1) _can_ see.
