-pipe
Use pipes rather than temporary files for communication between the various stages of compila-
tion. This fails to work on some systems where the assembler is unable to read from a pipe; but
the GNU assembler has no trouble.
-help

-v

is also specified then command line options which have no documentation associated with them
will also be displayed.
-target-help
Print (on the standard output) a description of target specific command line options for each tool.
-version
Display the version number and copyrights of the invoked GCC.

4.3. Compiling C++ Programs

C++ source files conventionally use one of the suffixes
C++ header files often use
files with these names and compiles them as C++ programs even if you call the compiler the same
way as for compiling C programs (usually with the name
However, C++ programs often require class libraries as well as a compiler that understands the C++
language--and under some circumstances, you might want to compile programs or header files from
standard input, or otherwise without a suffix that flags them as C++ programs. You might also like to
precompile a C header file with a
calls GCC with the default language set to C++, and automatically specifies linking against the C++
library. On many systems,
When you compile C++ programs, you may specify many of the same command-line options that you
use for compiling programs in any language; or command-line options meaningful for C and related
languages; or options that are meaningful only for C++ programs. Section 4.4 Options Controlling C

4.4. Options Controlling C Dialect

The following options control the dialect of C (or languages derived from C, such as C++ and
Objective-C) that the compiler accepts:
-ansi
In C mode, support all ISO C90 programs. In C++ mode, remove GNU extensions that conflict
with ISO C++.
This turns off certain features of GCC that are incompatible with ISO C90 (when compiling C
code), or of standard C++ (when compiling C++ code), such as the
and predefined macros such as
