 /*
 This test program is typically run indirectly, by the "wuffs test" or "wuffs
 bench" commands. These commands take an optional "-mimic" flag to check that
 Wuffs' output mimics (i.e. exactly matches) other libraries' output, such as
 giflib for GIF, libpng for PNG, etc.

 To manually run this test:

 for CC in clang gcc; do
   $CC -std=c99 -Wall -Werror adler32.c && ./a.out
   rm -f a.out
 done

 Each edition should print "PASS", amongst other information, and exit(0).

 Add the "wuffs mimic cflags" (everything after the colon below) to the C
 compiler flags (after the .c file) to run the mimic tests.

 To manually run the benchmarks, replace "-Wall -Werror" with "-O3" and replace
 the first "./a.out" with "./a.out -bench". Combine these changes with the
 "wuffs mimic cflags" to run the mimic benchmarks.
