Nope, at least not in R from CRAN:

Makevars:
all:
	echo R_HOME: $(R_HOME)

[...]
echo R_HOME: c:/PROGRA~1/R/R-212~1.2
R_HOME: c:/PROGRA~1/R/R-212~1.2

But I see that you have custom rhome setting (BBS...) so changes are that is the culprit - the rhome for that R build is set incorrectly to contain backslashes.

Cheers,
Simon
