Compilers
GCC
From wikipedia,
"GCC (GNU Compiler Collection) is a set of compilers for various language (C, C++, Objective-C, Objective-C++, Fortran, Java and Ada) produced by the GNU Project."
gcc
GNU project C and C++ compiler. When used for C++ compilation, it internally calls g++ but it does not point all the standard C++ libraries. Make sure that you include -lstdc++ in this case. When GCC is compiled with Fortran language support, gcc recognizes Fortran source codes (.f, .for, .ftn, .f90, .f95 and .f03) and can compile them.[1]

gfortran

g77
g77 is the ancestor of gfortran and was included in GCC prior to version 4.[2]
