Yes, R has been built in 64-bit mode on amd64 Solaris 10 (and it is not
going to work on x86, is it?). As far as I can see I used the SunStudio
11 compilers (which the box shipped with: there is also SunStudio 12 on
there) with
blackhawk% cat config.site
CC="cc -xc99 -xarch=amd64"
CFLAGS=-'O -xlibmieee'
F77="f95 -xarch=amd64"
FFLAGS=-O4

[3,] 0.4771213 0.7781513
(It's a pretty bare build, without either readline or GNU iconv.)

I suppose we are just supposed to know that '5.8' and '8.2' mean 11.
As I recall there was a good reason why I reduced the optimization level
-- I used -xO5 and -O5 on Sparc Solaris and the SunStudio x86_64 Linux
compilers so I suspect that something did not work at those levels.
