GC_CHECK_NOT_FREE/USE_KKCC makes build fail

Hello, I've got the very latest CVS source, and the build fails due to GC_CHECK_NOT_FREE being undefined. Here is the relevant snippet from the make output: === [...] alloc.c: In function `mark_object': alloc.c:3376: warning: implicit declaration of function `GC_CHECK_NOT_FREE' [...] /usr/bin/ld: Undefined symbols: _GC_CHECK_NOT_FREE /usr/bin/ld: warning unused multiple definitions of symbol _tgoto tparam.o definition of _tgoto in section (__TEXT,__text) /usr/lib/libcurses.dylib(tgoto.o) unused definition of _tgoto /usr/bin/ld: warning unused multiple definitions of symbol _matherr floatfns.o definition of _matherr in section (__TEXT,__text) /usr/lib/libcurses.dylib(s_matherr.o) unused definition of _matherr make[1]: *** [xemacs] Error 1 make: *** [src] Error 2 === Here's relevant bits from alloc.c: === #ifdef USE_KKCC /* The following functions implement the new mark algorithm. They mark objects according to their descriptions. They are modeled on the corresponding pdumper procedures. */ static void mark_struct_contents (const void *data, const struct sized_memory_description *sdesc, int count); #define GC_CHECK_NOT_FREE(lheader) \ gc_checking_assert (LHEADER_IMPLEMENTATION (lheader)->basic_p || \ ! ((struct lcrecord_header *) lheader)->free) === and: === #ifndef USE_KKCC /* We handle this separately, above, so we can mark free objects */ GC_CHECK_NOT_FREE (lheader); #endif /* not USE_KKCC */ === It seems you're damned if you define USE_KKCC and damned if you don't. :) I'm not yet familiar enough with the source to know what to fix.
