Environment Variables (The GNU Fortran Compiler)

### 2.12 Environment variables affecting `gfortran` ¶

The `gfortran` compiler currently does not make use of any environment variables to control its operation above and beyond those that affect the operation of `gcc`.

See Environment Variables Affecting GCC in Using the GNU Compiler Collection (GCC), for information on environment variables.

See Runtime: Influencing runtime behavior with environment variables, for environment variables that affect the run-time behavior of programs compiled with GNU Fortran.
