Why does the OpenSSL compilation fail on Win32 with VC++?
Sometimes, you may get reports from VC++ command line (cl) that it can’t find standard include files like stdio.h and other weirdnesses. One possible cause is that the environment isn’t correctly set up. To solve that problem for VC++ versions up to 6, one should run VCVARS32.BAT which is found in the ‘bin’ subdirectory of the VC++ installation directory (somewhere under ‘Program Files’). For VC++ version 7 (and up?), which is also called VS.NET, the file is called VSVARS32.BAT instead. This needs to be done prior to running NMAKE, and the changes are only valid for the current DOS session.
