-.Sp
-But one note about C++ programs only (not C). `\|\c
-.B \-traditional\c
-\&\|' has one additional effect for C++: assignment to
-.B this
-is permitted. This is the same as the effect of `\|\c
-.B \-fthis\-is\-variable\c
-\&\|'.
.TP
.B \-traditional\-cpp
Attempt to support some aspects of traditional C preprocessors.
\&\|' by default on some target systems
but not others.)
.TP
-.B \-fenum\-int\-equiv
-Permit implicit conversion of \c
-.B int\c
-\& to enumeration types (C++
-only). Normally GNU C++ allows conversion of \c
-.B enum\c
-\& to \c
-.B int\c
-\&,
-but not the other way around.
-.TP
.B \-fexternal\-templates
Produce smaller code for template declarations, by generating only a
single copy of each template function where it is defined (C++ only).
\&\|', all template instantiations are
explicitly internal.
.TP
-.B \-fall\-virtual
-Treat all possible member functions as virtual, implicitly. All
-member functions (except for constructor functions and
-.B new
-or
-.B delete
-member operators) are treated as virtual functions of the class where
-they appear.
-.Sp
-This does not mean that all calls to these member functions will be
-made through the internal table of virtual functions. Under some
-circumstances, the compiler can determine that a call to a given
-virtual function can be made directly; in these cases the calls are
-direct in any case.
-.TP
.B \-fcond\-mismatch
Allow conditional expressions with mismatched types in the second and
third arguments. The value of such an expression is void.
.TP
-.B \-fthis\-is\-variable
-Permit assignment to \c
-.B this\c
-\& (C++ only). The incorporation of
-user-defined free store management into C++ has made assignment to
-`\|\c
-.B this\c
-\&\|' an anachronism. Therefore, by default it is invalid to
-assign to \c
-.B this\c
-\& within a class member function. However, for
-backwards compatibility, you can make it valid with
-`\|\c
-.B \-fthis-is-variable\c
-\&\|'.
-.TP
.B \-funsigned\-char
Let the type \c
.B char\c
.B \-Wparentheses
Warn if parentheses are omitted in certain contexts.
.TP
-.B \-Wtemplate\-debugging
-When using templates in a C++ program, warn if debugging is not yet
-fully available (C++ only).
-.TP
.B \-Wall
All of the above `\|\c
.B \-W\c
Warn if anything is declared more than once in the same scope, even in
cases where multiple declaration is valid and changes nothing.
.TP
-.B \-Wnested-externs
-Warn if an \c
-.B extern\c
-\& declaration is encountered within an function.
-.TP
-.B \-Wenum\-clash
-Warn about conversion between different enumeration types (C++ only).
-.TP
.B \-Wlong-long
Warn if
