Error allocating mg_context on mg_start

[GoogleCodeExporter]

It seems that there is an error on allocating mg_context inside mg_start:

actual -> ctx = (struct mg_context *) calloc(1, sizeof(*ctx));

corrected -> ctx = (struct mg_context *) calloc(1, sizeof(ctx));

Instead of allocating memory for the structure it's allocating only memory for 
a pointer to a structure.

Please output sizeof(*ctx) and sizeof(ctx) and compare.

I did and the result is:
printf("%d : %d\n", sizeof(ctx), sizeof(*ctx)); -> 4 : 1288

if we only allocate memory for a pinter we should not use it as it is done now:

  ctx = (struct mg_context *) calloc(1, sizeof(*ctx));
  ctx->user_callback = user_callback; <<<< writing to unallocated memory
  ctx->user_data = user_data; <<<< writing to unallocated memory

This is done with mingw 4.6.2
