[R] Problem with checks on R/4.0.0

[Simon Michnowicz]

Dear R Group,
I can build a simple R/4.0.0 OK using   gcc/8.1.0, but when I tried to link
it with  the Intel MKL,  'make check' produced this error

tail tests/reg-tests-1d.Rout.fail

> (m <- cbind(0, c(NA, 0), 0:-1))
     [,1] [,2] [,3]
[1,]    0   NA    0
[2,]    0    0   -1
> nTypes <- eval(formals(base::norm)$type) # "O" "I" "F" "M" "2"
> stopifnot(is.na( print(vapply(nTypes, norm, 0., x = m)) )) # print():
show NA *or* NaN
 O  I  F  M  2
NA NA  1 NA NA
Error: is.na(print(vapply(nTypes, norm, 0, x = m))) are not all TRUE
Execution halted

Is this a significant error?
 There may be differences in how NaN are treated between GNU and MKL that
caused this.

regards
