This patch verifies that the header files don't accidentally require
<stdio.h> or <string.h>.
2017-10-29 Bruno Haible <br...@clisp.org>
crypto/*: Verify that the header file is self-contained.
* tests/test-gc-*.c: Include the module's header file immediately after
<config.h>.
* tests/test-hmac-*.c: Likewise.
* tests/test-arcfour.c: Likewise.
* tests/test-arctwo.c: Likewise.
* tests/test-des.c: Likewise.
* tests/test-md2.c: Likewise.
* tests/test-md4.c: Likewise.
* tests/test-md5.c: Likewise.
* tests/test-rijndael.c: Likewise.
* tests/test-sha1.c: Likewise.
* tests/test-sm3.c: Likewise.
