The other GCC-based Fortran compiler
gfortran is not g95
gfortran is the Fortran (77/90/95/2003/...) compiler that is part of GCC (the GNU Compiler Collection).
g95 is another Fortran compiler, which is based on GCC.
In early 2000 Andrew Vaught started g95, a project to create a free software Fortran 95 compiler using the GCC backend. This was a collaborative project for two years, but in late 2002 Andrew decided to become sole developer of g95. The gfortran project was created in January 2003 as a fork from the GPL-licensed g95 source code at that time, in order to allow for cooperative development and integration with the GCC codebase.
Since that time, Andrew has continued development of g95 independently, and the codebases of g95 and gfortran have significantly diverged. Thus, the gfortran team is unable to provide support or advice regarding g95.
