Avro fails to compile for C

AVRO for C fails to compile.

Could be duplicate of AVRO-778

First instance of failure (of many) occures in avro_schema_to_header :

static int avro_schema_to_header(avro_schema_t schema, specific_ctx * ctx)
{
size_t i;
FILE *fp = ctx->header;

indent(ctx, fp);
ctx->depth++;

if (is_avro_primitive(schema) && !ctx->name) {
<function continues....>

ctx has no member name.

The definition of the struct above is :
enum specific_state {
START_STATE,
};
typedef enum specific_state specific_state;

struct specific_ctx {
FILE *header;
FILE *source;
int depth;
specific_state state;
};
typedef struct specific_ctx specific_ctx;

So every instance of ctx->name fails.....
