GPL components in libgcrypt 1.4.1

[vipul aggarwal]

Hi,
 
I am using libgrcypt
for the first time.
I have some
question regarding the GPL components in libgcrypt 1.4.1.
 
	1. As per the README of libgcrypt,
“The helper programs (gcryptrnd and getrandom) as well as
the documentation are distributed under the terms of the GNU General Public
License (GPL)”
 
But, it seems following files are also under GPL.
./src/dumpsexp.c
./tests/random.c
./tests/prime.c
./tests/ac-schemes.c
 
I was also unable to make/compile the libgcrypt
without these 4 files.
 
Can anyone guide as to whether these files come
under GPL or not?
 
Thanks for the answers in advance.
 
Cheers
Vipul
