Compiler Command-line Options
2.1.76 --friend_injection, --no_friend_injection
This option controls the visibility of friend declarations in C++.
In C++, it controls whether or not the name of a class or function that is declared only
in friend declarations is visible when using the normal lookup mechanisms.
When friend names are declared, they are visible to these lookups. When friend names
are not declared as required by the standard, function names are visible only when using
argument-dependent lookup, and class names are never visible.
Note
The option --friend_injection is provided only as a migration aid for legacy source
code that does not conform to the C++ standard. Its use is not recommended.
Mode
This option is effective only if the source language is C++.
Default
The default is --no_friend_injection.

2.1.77 -g
This option enables the generation of debug tables for the current compilation.
The compiler produces the same code regardless of whether -g is used. The only
difference is the existence of debug tables.
Using -g does not affect optimization settings. By default, using the -g option alone is
equivalent to:
-g --dwarf3 --debug_macros
