+	* mt19937ar.c: Add to support common font names in all
+	platforms when SOURCE_DATE_EPOCH is suitably set. A pseudo
+	random number generating program coded by Takuji Nishimura and
+	Makoto Matsumoto.
+	* README: Add a subject "11. Random number generating function".
+	* mem.h: Add "#define srand(x) init_genrand((x))", etc. because
+	it is the only common header file for dpxcrypt.c, pdfencrypt.c,
+	and pdffont.c, which use rand().
+	* Makefile.am: Add mt19937ar.c.
+	* configure.ac: Version 20191114.

+11. Random number generating function
+
+   Prefixes of font names are calculated by using a function which
+   generates pseudo random numbers. In order to obtain a unique
+   prefix on all platforms when current time is common, a special
+   function MT19937, coded by Takuji Nishimura and Makoto Matsumoto,
+   is used. The header of the C program by Takuji Nishimura and

+
+   A C-program for MT19937, with initialization improved 2002/1/26.
+   Coded by Takuji Nishimura and Makoto Matsumoto.
+
+   Before using, initialize the state by using init_genrand(seed)  
+   or init_by_array(init_key, key_length).
