rather than '#ifdef' BIG_ENDIAN_HOST. Harmless as we explicitly
define BIG_ENDIAN_HOST to 1 when we need it, but needed for OSX fat
builds when we define BIG_ENDIAN_HOST to another macro.
rijndael.c, rndunix.c, sha256.c, cast5.c, idea-stub.c, rmd160.c, rndw32.c,
sha512.c, md5.c, rmd160test.c, rsa.c, tiger.c: Edit all preprocessor
instructions to remove whitespace before the '#'. This is not required by
C89, but there are some compilers out there that don't like it.
* random.c (fast_random_poll): Only use times() if we HAVE_TIMES.
* sha512.c, tiger.c: Use the U64_C() macro to specify 64-bit constants.
U64_C is defined in include/types.h and uses the correct suffix depending
on the underlying type of u64.
* idea-stub.c (load_module): Catch an error if the idea module file is
unloadable for some reason (unreadable, bad permissions, etc.)
* md.c (string_to_digest_algo): Give a warning about TIGER192 not being
part of OpenPGP.
