  Changes between 0.9.3a and 0.9.4
 
+  *) The -DPLATFORM="\"$(PLATFORM)\"" definition and the similar -DCFLAGS=...
+     (both in crypto/Makefile.ssl for use by crypto/cversion.c) caused
+     problems not only on Windows, but also on some Unix platforms.
+     To avoid problematic command lines, these definitions are now made
+     in auto-generated file crypto/buildinf.h, which also defines DATE
+     and thus replaces crypto/date.h.
+     [Bodo Moeller]

   *) MIPS III/IV assembler module is reimplemented.
