MODULE_GC_KLUDGE conditional compilation blocks

[Ian Hulin]

Hi all,
We have these blocks in our C++ code base:
$ git grep -A 5 MODULE_GC_KLUDGE
lily/include/ly-module.hh:#define MODULE_GC_KLUDGE
lily/include/ly-module.hh-
lily/include/ly-module.hh-#endif /* LY_MODULE_HH */
lily/include/ly-module.hh-
--
lily/ly-module.cc:#ifdef MODULE_GC_KLUDGE
lily/ly-module.cc-Protected_scm anonymous_modules = SCM_EOL;
lily/ly-module.cc-bool perform_gc_kludge;
lily/ly-module.cc-#endif
lily/ly-module.cc-
lily/ly-module.cc-void
--
lily/ly-module.cc:#ifdef MODULE_GC_KLUDGE
lily/ly-module.cc-  for (SCM s = anonymous_modules;
lily/ly-module.cc-       scm_is_pair (s);
lily/ly-module.cc-       s = scm_cdr (s))
lily/ly-module.cc-    {
lily/ly-module.cc-      SCM module = scm_car (s);
--
lily/module-scheme.cc:#ifdef MODULE_GC_KLUDGE
lily/module-scheme.cc-  clear_anonymous_modules ();
lily/module-scheme.cc-#endif
lily/module-scheme.cc-
lily/module-scheme.cc-  return SCM_UNSPECIFIED;
lily/module-scheme.cc-}
$
As I understand it, these are to get round problems with Guile pre 
V1.8,7, which we no longer support.  Is it now safe to delete this code?

Cheers,

Ian Hulin
