gfortran which is part of GCC supports modules (this is because Fortran the language supports modules).

If you meant modules for C or C++, no (as far as I know), probably because C and C++ have no standard for modules. In a recent talk Bjarne Stroustroup talks about his hope that C++17 will include support for modules https://www.youtube.com/watch?v=2egL4y_VpYg

It probably will once the C++ committee figures out how they want to do it...
