What do I have to do to build Windows Unicon?
At present the recommended compiler is GNU C 2.95.2 with the Ming libraries. MS Visual C++ 6.0 was used recently, and earlier versions of VC++ would work with minor changes (such as, perhaps, disabling the ODBC functions). Other C compilers will require nontrivial effort to develop new configuration files under the config/win32 directory, comparable to (and possibly starting from) config/win32/gcc or config/win32/msvc.
