// EnvironmentDefaults is a list of default values for environment variables
// that may be specified at compile time and set by the runtime during
// program startup if the variable is not already present in the environment.
// EnvironmentDefaults is intended to allow options controlled by environment
// variables to also be set on the command line at compile time without needing
// to define option-specific runtime calls or duplicate logic within the
// runtime. For example, the -fconvert command line option is implemented in
// terms of an default value for the FORT_CONVERT environment variable.
