Gaius Mulley a0004feb87 PR modula2/114529 Avoid ODR violations in bootstrap translated sources 
This patch changes the bootstrap tool mc to avoid redefining any data
types and therefore preventing ODR violations.  All exported opaque type
usages are implemented as void *.  Local opaque type usages (static
functions containing opaque type parameters) use the full declaration.
mc casts usages between void * and full opaque type as necessary.
The --extended-opaque option in mc has been disabled, as this generated
ODR violations.  The extended-opaque option inlined all declarations in
the translated implementation module.  As this is no longer used there
is now a .h file for each .def file and a .cc file for every .mod file.
This results in more Makefile rules for the ppg tool in Make-maintainer.in.

README 

This directory contains the GNU Compiler Collection (GCC).

The GNU Compiler Collection is free software.  See the files whose
names start with COPYING for copying permission.  The manuals, and
some of the runtime libraries, are under different terms; see the
individual source files for details.

The directory INSTALL contains copies of the installation information
as HTML and plain text.  The source of this information is
gcc/doc/install.texi.  The installation information includes details
of what is included in the GCC sources and what files GCC installs.

See the file gcc/doc/gcc.texi (together with other files that it
includes) for usage and porting information.  An online readable
version of the manual is in the files gcc/doc/gcc.info*.

See http://gcc.gnu.org/bugs/ for how to report bugs usefully.

Copyright years on GCC source files may be listed using range
