[R] make check-all failed on SLES8 for x86_64

[Liaw, Andy]

Hi all,

I've only now noticed that on our Opteron boxes running Suse Enterprise
Server 8 that R-2.0.1 did not pass make chek-all.  It bombed in
tests/lapack.R at:

> eigenok <- function(A, E, Eps = 1000 * .Machine$double.eps) {
    V <- E$vect
    lam <- E$values
    stopifnot(abs(A %*% V - V %*% diag(lam)) < Eps,  .... [TRUNCATED] 

> Ceigenok <- function(A, E, Eps = 1000 * .Machine$double.eps) {
    V <- E$vect
    lam <- E$values
    stopifnot(Mod(A %*% V - V %*% diag(lam)) < Eps, .... [TRUNCATED] 

> sm <- cbind(1, 3:1, 1:3)

> eigenok(sm, eigen(sm))
Error: abs(A %*% V - V %*% diag(lam)) < Eps is not TRUE

This is using:
~/R-2.0.1> gcc -v
Reading specs from /opt/gcc33/lib64/gcc-lib/x86_64-suse-linux/3.3/specs
Configured with: ../configure --enable-threads=posix --prefix=/opt/gcc33

gcc version 3.3 20030312 (prerelease) (SuSE Linux)

compiled with the following setting:

R is now configured for x86_64-unknown-linux-gnu

  Source directory:          .
  Installation directory:    /usr/local

  C compiler:                gcc  -g -O2
  C++ compiler:              g++  -g -O2
  Fortran compiler:          g77  -g -O2

  Interfaces supported:      X11, tcltk
  External libraries:        readline
  Additional capabilities:   PNG, JPEG
  Options enabled:           R profiling

  Recommended packages:      yes

Actually, I've only noticed this when the samething happens on a RH-based
box (same hardware), using:
$ gcc -v
Reading specs from /usr/lib/gcc-lib/x86_64-redhat-linux/3.2.3/specs
Configured with: ../configure --prefix=/usr --mandir=/usr/share/man

Thread model: posix
gcc version 3.2.3 20030502 (Red Hat Linux 3.2.3-24)

I'd very much appreciate any pointers!

Best,
Andy
