Memory leak issue occur in function mg_start

[GoogleCodeExporter]

What steps will reproduce the problem?
Call function mg_start when parameter "options" contain same-name option items, 
memory leak occur at this line:
    ctx->config[i] = mg_strdup(value);
To fix:
    free memory if config[i] have assigned value, new code:
    if (ctx->config[i] != NULL)
        free(ctx->config[i]);
    ctx->config[i] = mg_strdup(value);

What is the expected output? What do you see instead?
be independent of system. found the issue by code review

The right way is to fail rather then silently change the value.
It is an error to pass duplicate option values, and depending on the order of 
options.
