These warnings are fixed now:

cbits/http.c: In function ?_http_print_html?:

cbits/http.c:762:0:
     warning: passing argument 2 of ?getline? from incompatible pointer type

/usr/include/stdio.h:673:0:
     note: expected ?size_t * __restrict__? but argument is of type ?unsigned int *?
cbits/http.c: In function ?_http_print_html?:

     warning: passing argument 2 of ?getline? from incompatible pointer type

/usr/include/stdio.h:673:0:
