This is the GNU Fortran compiler, which compiles Fortran on platforms supported by the gcc compiler.

Abseil is an open-source collection of C++ library code designed to augment the C++ standard library. The Abseil library code is collected from Google's C++ codebase and has been extensively tested and used in production. In some cases, Abseil provides pieces missing from the C++ standard; in others, Abseil provides alternatives to the standard for special needs.

lfanew is a tool manipulating the e_lfanew header field in MZ (DOS) binaries. It can - add a .e_lfanew field to an MZ binary, allowing it to be used as a DOS loader stub for a NE or PE binary; - stubify a NE/PE binary by combining it with an MZ stub; - extract a NE/PE binary from a stubified MZ/NE/PE binary pair.

This is the GNU Fortran compiler, which compiles Fortran on platforms supported by the gcc compiler.

This is the GNU D compiler, which compiles D on platforms supported by gcc. It uses the gcc backend to generate optimised code.

It attaches to a running Wayland session, creates virtual input devices, and exposes a single display via the RFB protocol. The Wayland session may be a headless one, so it is also possible to run wayvnc without a physical display attached.
