Did you enable threads? `grep PTHREAD scmconfig.h` to check.
Here is the current definition of GC_INIT ():
/* Portable clients should call this at the program start-up. More */
/* over, some platforms require this call to be done strictly from the */
/* primordial thread. */
#define GC_INIT() { GC_INIT_CONF_DONT_EXPAND; /* pre-init */ \
GC_INIT_CONF_FORCE_UNMAP_ON_GCOLLECT; \
GC_INIT_CONF_MAX_RETRIES; \
GC_INIT_CONF_FREE_SPACE_DIVISOR; \
GC_INIT_CONF_FULL_FREQ; \
GC_INIT_CONF_TIME_LIMIT; \
GC_INIT_CONF_MAXIMUM_HEAP_SIZE; \
GC_init(); /* real GC initialization */ \
GC_INIT_CONF_ROOTS; /* post-init */ \
GC_INIT_CONF_IGNORE_WARN; \
GC_INIT_CONF_INITIAL_HEAP_SIZE; }
So you see it does GC_init(). That was not always the case in previous
versions, AFAIK.
