I noticed some gcc warnings when configuring --pdump, but NOT --use-kkcc. Briefly, they are: 2970: kkcc_gc_stack_init defined but not used 2985: kkcc_gc_stack_free defined but not used 3037: kkcc_gc_stack_pop defined but not used 3046: No previous prototype for kkcc_gc_stack_push_lisp_object. The first 3 are easy to fix, so I was just going to submit the patch myself. However, the last one has me a little confused. The prototype is declared in lisp.h inside an #ifdef USE_KKCC block. Also, all uses of kkcc_gc_stack_push_lisp_object are inside of #ifdef USE_KKCC blocks ... except for on line 3329, where mark_object_maybe_checking_free is #define'd to it if not ERROR_CHECK_GC, regardless of --use-kkcc or not. So are all uses of mark_object_maybe_checking_free inside of #ifdef USE_KKCC blocks? I'm not sure. Part of my confusion stems from the fact that the #ifdef USE_KKCC on line 3322 is inside of the #ifdef USE_KKCC starting on line 3298! Somebody who knows what is going on (i.e., not me) had better fix this. -- Jerry James http://www.ittc.ku.edu/~james/
