You could use MinGW, a Windows port of GCC. It can generate console applications as well as GUI applications. You almost certainly will be able to compile old C programs that don't rely on any uncommon library. Currently the best MinGW distribution is TDM-GCC (). Try also Code::Blocks (), it is an excellent multiplatform IDE that supports a lot of different compilers, including GCC/MonGW.
