R devel - Apr 2017 - TEXINFO error when building R-3.4.0

Hello.

I am trying to build 64 bit R-3.4.0 (specifically
R-patched_2017-04-23) on Windows 64 and have run into an issue with
building the html files. I am using Rtools34 version 1962, the texinfo
zip from <http://www.stats.ox.ac.uk/pub/Rtools/> unzipped into
C:\R\texinfo, and Strawberry perl 5.24.1.1-64bit. In my MkRules.local
I have the following, which worked for building R in 3.3.x:

# set this to YES to build static HTML help
BUILD_HTML = YES

# unset this if you are *not* using MiKTeX
MIKTEX = TRUE
# Recent MiKTEX does not provide texi2dvi and needs something like
TEXI2DVI = TEXINDEX=C:/Rtools/bin/texindex.exe texify

# for texinfo >= 5.1. If the texinfo files are installed at
/packages/texinfo,
TEXI2ANY = C:/Strawberry/perl/bin/perl.exe -I/C:/R/texinfo C:/R/texinfo/texi2any
# if you do not have texinfo (default),
# TEXI2ANY = missing

Nevertheless, while building R-3.4 I get the following error:


------ Making HTML documentation ------

If it helps, Convert seems to be found in C:\R\texinfo\Texinfo\Convert
which is not in the list of @INC. Any and all help would be
appreciated.

Thank you,

The fault was mine.

-I/C:/R/texinfo should have been -IC:/R/texinfo

Thank you,
