desired, GNU bc can be built with CygWin32 without change.
+ Installation
+ ------------
+
+ There's currently no real installation procedure for Win32. There are,
+ however, some suggestions:
+
+ - do nothing. The include files are found in the inc32/ subdirectory,
+ all binaries are found in out32dll/ or out32/ depending if you built
+ dynamic or static libraries.
+
+ - do as is written in INSTALL.Win32 that comes with modssl:
+
+ $ md c:\openssl
+ $ md c:\openssl\bin
+ $ md c:\openssl\lib
+ $ md c:\openssl\include
+ $ md c:\openssl\include\openssl
+ $ copy /b inc32\* c:\openssl\include\openssl
+ $ copy /b out32dll\ssleay32.lib c:\openssl\lib
+ $ copy /b out32dll\libeay32.lib c:\openssl\lib
+ $ copy /b out32dll\ssleay32.dll c:\openssl\bin
+ $ copy /b out32dll\libeay32.dll c:\openssl\bin
+ $ copy /b out32dll\openssl.exe c:\openssl\bin
+
+ Of course, you can choose another device than c:. C: is used here
+ because that's usually the first (and often only) harddisk device.
+ Note: in the modssl INSTALL.Win32, p: is used rather than c:.
