	lang/gcc gcc-4.6.3_1
	print/texinfo texinfo-5.2.20130926_1
>Description:
	the build of lang/gcc fails on building the documentation if
	print(texinfo is installed (the usual "@itemx must follow @item"
	error messages are seen).

>How-To-Repeat:
	type make
>Fix:
	This problem was fixed in gcc-4.6.4. Short of updating lang/gcc,
	I extracted the neccessary changes from the gcc-4.6.4 source.
	The following patch should be dropped into lang/gcc/files (with
	or without processing by splitpatch.pl).

	NOTE this is an additional patch for lang/gcc/files/, not a patch
	agains the ports tree
