Re: [libmicrohttpd] External select mode limited to 1024 FDs

It does, it's just a bit tricky to do right. You need to make sure you
set the correct #defines before anything else consistently across the build:

#if LINUX
#include <features.h>
#if (__GLIBC__ > 2) || (__GLIBC__ == 2 && __GLIBC_MINOR__ >= 2)
# include <bits/types.h>
# undef __FD_SETSIZE
# define __FD_SETSIZE 8192
#endif
#else
#define FD_SETSIZE 65536
#endif

Do this before you #include anything else in all C files, and you should
be fine.
