The extra_headers member declaration depends on
ENABLE_FEATURE_WGET_LONG_OPTIONS:
/* Globals */
struct globals {
...
#if ENABLE_FEATURE_WGET_LONG_OPTIONS
char *post_data;
char *extra_headers;
#endif
...
} FIX_ALIASING;
thus, the free(G.extra_headers) statement must be stripped off by
preprocessor if ENABLE_FEATURE_WGET_LONG_OPTIONS is zero. May I keep
on with the previous approach, or do you have another one in mind?
