Comment (by rl1987):

 Are you using GCC-based toolchain instead of LLVM-based toolchain? When I
 run configure, I am getting the following lines:

 {{{
 checking size of int8_t... 0
 checking size of int16_t... 0
 checking size of int32_t... 0
 checking size of int64_t... 0
 checking size of uint8_t... 0
 checking size of uint16_t... 0
 checking size of uint32_t... 0
 checking size of uint64_t... 0
 checking size of intptr_t... 0
 checking size of uintptr_t... 0
 checking size of char... 0
 checking size of short... 0
 checking size of int... 0
 checking size of long... 0
 checking size of long long... 0
 checking size of __int64... 0
 checking size of void *... 0
 checking size of time_t... 0
 checking size of size_t... 0
 checking size of pid_t... 0
 }}}

 Any idea how configuring with libscrypt causes configure to think that all
 of above are 0? I tried to do some hacking to work around this issue (see
 https://github.com/rl1987/tor/commits/bug1641_hax), but no luck so far.
 Editing configure.ac to check type sizes early fixes this exact problem,
 but causes error about 2's complement number to surface.
