static void * hash_mem_alloc(size_t datalen, size_t size)
{
     if (sizeof(HASHDATA) == datalen)
     {
         return BJAM_MALLOC_RAW(size);
     }
     else
     {
         return BJAM_MALLOC(size);
     }
}

When bjam is using a strings hash table the hash entries only contain 
the string key. The above checks for that and allocates those entries 
outside the boehm collector (BJAM_MALLOC_RAW).
