For me this fixes it:

with Python 2, I have

sudo apt-get install python-dev  \
     build-essential libssl-dev libffi-dev \
     libxml2-dev libxslt1-dev zlib1g-dev \
     ...

with Python 3, I need

sudo apt-get install python3 python-dev python3-dev \
     build-essential libssl-dev libffi-dev \
     ...

Installing python-dev python3-dev fixes it for me!

Use PyCryptodome instead of pycrypto. pycrypto is discontinued and is no longer actively supported. PyCryptodome exposes almost the same API as pycrypto (source).

The file include\pyport.h in Python installation directory does not have #include < stdint.h > anymore. This leaves intmax_t undefined.

A workaround for Microsoft VC compiler is to force include stdint.h via OS environment variable CL:

  1. Open command prompt
  2. Setup VC environment by runing vcvars*.bat (choose file name depending on VC version and architecture)
  3. set CL=-FI"Full-Path\stdint.h" (use real value for Full-Path for the environment)
  4. pip install pycrypto

Thanks to user1960422's answer.
PowerShell steps for pycrypto 2.6.1 (via simple-crypt) / Python 3.6 / Windows 10:

$env:VCINSTALLDIR="C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC"
$env:CL="-FI`"$env:VCINSTALLDIR\INCLUDE\stdint.h`""

Successful simple-crypt / pycrypto install

I also needed to follow the answer in: https://stackoverflow.com/a/24822876/8751739 to fix a winrandom module error.
