In GCC, there are many options begin with "g", "W", "f" or "m".

  • "g": -glevel -ggdb
  • "W": -Wa, -Wl, -Wall
  • "f": -fno-access-control, -fno-rtti
  • "m": -masm

I don't know the full names and meanings of "g", "W", "f", "m".

  • G → GCC debugging (enables debugging messages)

  • W → warning (w disables all warning messages, Wall enables all warnings)

  • F → function (deals with functions that are treated by the compiler)

  • M → make (outputs a tree map of the source file and all included file, kind of a Makefile).
