Changing the above line, to
#if defined(__i386__) || defined(__x86_64__) || defined(__vax__) || defined
(_M_IX86) || defined(_M_X64)
Caused my vc build of the new dyna_1010, to go from 2010k, to 2391k on my
system. The first was set in md4.c, md5.c, md5_go.c (which my dynamic
uses), and md5_eq.c
The 'wrong' code worked, but it was doing byte/byte swapping, from Intel
format, back to Intel format. Not too efficient when compared to a int
assignment. There is a comment, listing this is just an optimization, and
nothing 'fails' if it gets it wrong. But the #define is woefully lacking.
Even the way I have it, it is greatly lacking.
Jim.
