As the environment variables refer to the corresponding filename in the make/fcmcfg directory it is straightforward to create a build configuration for other environments. Take a copy of an existing file and modify it as necessary. It's also possible to alter compile options by the use of additional environment variables (see below). Which approach you use depends on your personal preference. Be aware however that the optimization compiler flags in the provided configuration files are the recommended ones. It is impossible to test all combinations of compiler flags so OpenIFS may become unstable or performance may reduce if higher optimizations are tried.
