Convert coreutils' rand.{c,h,m4} into modules. First step: move these files to gl/lib: lib/rand-isaac.c, lib/rand-isaac.h * lib/randint.c, lib/randint.h * lib/randperm.c, lib/randperm.h * lib/randread.c, lib/randread.h Step 2: add modules/rand* and remove now-unneeded .m4 files. * gl/modules/randint: New file. * gl/modules/randperm: New file. * gl/modules/randread: New file. * m4/randint.m4: Remove file. * m4/randperm.m4: Remove file. * m4/randread.m4: Remove file. Step 3: use the new modules * bootstrap.conf (gnulib_modules): Add randint and randperm. * m4/prereq.m4 (gl_RANDINT, gl_RANDREAD, gl_RANDPERM): Don't require; These have been removed. (gl_ROOT_DEV_INO): Don't require; already handled via bootstrap.conf. 2007-09-01 09:54:45 +02:00			`Description:`

randread: don't require -lrt Programs like 'sort' were linking to -lrt in order to get clock_gettime, but this was misguided: it wasted considerable resources while gaining at most 10 bits of entropy. Almost nobody needs the entropy, and there are better ways to get much better entropy for people who do need it. * gl/lib/rand-isaac.c (isaac_seed): Include <sys/time.h> not "gethrxtime.h". (isaac_seed): Use gettimeofday rather than gethrxtime. * gl/modules/randread (Depends-on): Depend on gettimeofday and not gethrxtime. * src/Makefile.am (mktemp_LDADD, shred_LDADD, shuf_LDADD, sort_LDADD): (tac_LDADD): Omit $(LIB_GETHRXTIME); no longer needed. 2010-07-16 14:02:08 -07:00			`gettimeofday`
