解决办法：
修改src\libtom\tomcrypt.h

#ifndef TOMCRYPT_H_
#define TOMCRYPT_H_
#define LTC_NO_PROTOTYPES
#include 
#include 
#include 
#include 
#include 
#include 
#include 

2、修改src\libtom\tomcrypt_cypher.h

3、修改setup.py

if __name__ == '__main__':
    if (sys.platform == 'win32' and sys.version_info[0] == 3 and
        'build' in sys.argv[1:]):
        PrintErr("\nSecond pass to allow 2to3 to fix nt.py. No cause for alarm.\n")
        touch("./lib/Crypto/Random/OSRNG/nt.py")
        core.setup(**kw)

4、重新安装

python setup.py install
