Matthew, Liu

first sorry for the delay in answering, but I was buried in an important 
project.

I can offer you a solution that was actually found by one of our customers, 
Tobias Reber from DKFZ (German Cancer Research Center).

I am appending a patch (generated by cvs diff -c ...) that I applied to R 
v1.6.2.

Then I typed the following two commands.

OBJECT_MODE=64 \
MAKE=gmake \
CC="cc -DSTDC" \
CXX="xlC" \
MAIN_LDFLAGS="-Wl,-brtl" \
SHLIB_LDFLAGS="-Wl,-G" \
F77="xlf" \
./configure \
--without-x \
--without-blas

OBJECT_MODE=64 gmake

After this I tested with "gmake check" and found no errors.

I have just retried the above on the following setup.
h/w p690+ 1.7GHz
[tstposp at j36 R]$ oslevel -r
5200-02
[tstposp at j36 R]$ lslpp -l | grep vac.C

I copied the r-help mailing list, but I am not sure whether I can post there. 
Could you please post this if you don't see it posted ? Thanks.
