Not to disagree with your patch, but how about imitating the C99
standard and add the following definitions to gc.h (next to the GC_word
typedef)?

#define GC_PRIdWORD "ld"
#define GC_PRIiWORD "li"
#define GC_PRIoWORD "lo"
#define GC_PRIuWORD "ld"
#define GC_PRIxWORD "lx"
#define GC_PRIXWORD "lX"

One of the print statements below would then look like

    GC_printf("Free list %lu (total size %"GC_PRIuWORD");\n",
	      i, GC_free_bytes[i]);

BTW, i is already long above, no cast needed.
