Bug #3231: Digest Does Not Build
http://redmine.ruby-lang.org/issues/3231

 Revisiting this one from a few weeks back.  MD5/rmd160/sha1/sha2 do not build using VC 2010.  They do build with Mingw (mingw + msys). See compiler logs below.
 
 Focusing on MD5 (they all have the same issue):
 
 extconf.h is generated like this:
 
 #ifndef EXTCONF_H
 #define EXTCONF_H
 #define HAVE_CONFIG_H 1
 #define HAVE_OPENSSL_MD5_H 1
 #endif
 
 Then in md5init.c:
 
 #include "digest.h"
 #if defined(HAVE_OPENSSL_MD5_H)
 #include "md5ossl.h"
 #else
 #include "md5.h"
 #endif
 
 Since extconf.h is never passed to the compiler, the error happens.  Adding this to the top of the file:
 
 #define HAVE_OPENSSL_MD5_H
 
 Fixes the issue. Clearly that's a hack, but I don't understand how extconf.h is used in building the extension since the only place it comes into play is in the generated makefile:
 
 $(OBJS): $(RUBY_EXTCONF_H)
 
 So not sure the solution, but the problem is that having openssl installed correctly breaks the VC digest extension build.
