gcov-io.h and libgcc GPL exception

[Joseph S. Myers]

gcov-io.h contains some functions that get used in libgcc2.c.  Shouldn't
it have the libgcc license exception?

	In addition to the permissions in the GNU General Public License, the
	Free Software Foundation gives you unlimited permission to link the
	compiled version of this file into combinations with other programs,
	and to distribute those combinations without any restriction coming
	from the use of this file.  (The General Public License restrictions
	do apply in other respects; for example, they cover modification of
	the file, and distribution when not linked into a combine
	executable.)

[Also, I notice that GPLv1, along with the old FSF address, has returned
to GCC with tradcpp.]
