+
+	* cplus-dem.c: yet another copy of this - maybe it should go into
+	libiberty ?
+	* ldgram.y: now -V and -v have different actions
+	* ldver.c: if -V, prints list of emulations compiled in
+	* ldmisc.c: support for cplus demangling
+
+
+Thu Feb 20 17:43:46 1992  Per Bothner  (bothner at cygnus.com)
+
+	* Makefile.in:  Change mkscript rule into one for ./mkscript
+	(for the sake of makes that don't realize they're the same).
+	* PORTING:  Add more details.
+	* genscripts.sh:  Add more tailorability of DATA_ALIGNMENT.

+/* This file exports one function
+
+   char *cplus_demangle (const char *name, int mode)
+
+   If NAME is a mangled function name produced by GNU C++, then
+   a pointer to a malloced string giving a C++ representation
+   of the name will be returned; otherwise NULL will be returned.
+   It is the caller's responsibility to free the string which
+   is returned.
+
+   If MODE > 0, then ANSI qualifiers such as `const' and `void' are output.
+   Otherwise they are not.
+   If MODE >= 0, parameters are emitted; otherwise not.
+
+   For example,
+   
+   cplus_demangle ("foo__1Ai",  0)	=> "A::foo(int)"
+   cplus_demangle ("foo__1Ai",  1)	=> "A::foo(int)"
+   cplus_demangle ("foo__1Ai", -1)	=> "A::foo"
+
+   cplus_demangle ("foo__1Afe",  0)	=> "A::foo(float,...)"
+   cplus_demangle ("foo__1Afe",  1)	=> "A::foo(float,...)"
+   cplus_demangle ("foo__1Afe", -1)	=> "A::foo"
