Subject: [PATCH 1/9] Fix visibility of GC_clear/set_mark_bit (unhide symbols)
* include/private/gc_priv.h (GC_clear_mark_bit, GC_set_mark_bit):
Declare as GC_API_PRIV (instead of GC_INNER) to make the symbol
externally visible to 3rd-party software (e.g., ECL).
* mark.c (GC_set_mark_bit, GC_clear_mark_bit): Remove GC_INNER (to
match the declaration).
