This chapter explains the following command-line options for language translation:

• -char
  Controls the default sign of the char data type.
• -defaults
  Controls whether the compiler uses additional environment variables to provide default settings.
• -encoding
  Specifies the default source encoding used by the compiler.
• -flag
  Specifies compiler #pragma as either on or off.
• -gccext
  Enables GCC (Gnu Compiler Collection) C language extensions.
• -gcc_extensions
  Equivalent to the -gccext option.
• -M
  Scans source files for dependencies and emit a Makefile, without generating object code.
• -make
  Scans source files for dependencies and emit a Makefile, without generating object code.
• -mapcr
  Swaps the values of the \n and \r escape characters.
• -MM
  Scans source files for dependencies and emit a Makefile, without generating object code or listing system #include files.
• -MD
  Scans source files for dependencies and emit a Makefile, generate object code, and write a dependency map.
• -MMD
  Scans source files for dependencies and emit a Makefile, generate object code, write a dependency map, without listing system #include files.
• -msext
  Allows Microsoft® Visual C++ extensions.
• -once
  Prevents header files from being processed more than once.
• -pragma
  Defines a pragma for the compiler.
• -relax_pointers
  Relaxes the pointer type-checking rules in C.
• -requireprotos
  Controls whether or not the compiler should expect function prototypes.
• -search
  Globally searches across paths for source files, object code, and libraries specified in the command line.
• -trigraphs
  Controls the use of trigraph sequences specified by the ISO/IEC standards for C and C++.
