[Rd] Build Portland Group Compiler

[Jennifer Lai]

Hi,
    I built R with Portland Group compiler, but I noticed one thing that 
when I ran configure for the first time on AMD machine, I got the 
following error:


checking whether the C compiler works... configure: error: cannot run C 
compiled programs.
If you meant to cross compile, use `--host'.
See `config.log' for more details.



so I tried to set host=x86_64-unknown-linux-gnu, which seems to work, 
except what puzzles me is that there is warning messages indicating C 
longs are 4 bytes.

% configure --host=x86_64-unknown-linux-gnu

configure: WARNING: assuming C ints are 4 byte on x86_64-unknown-linux-gnu
configure: WARNING: assuming C longs are 4 byte on x86_64-unknown-linux-gnu

Am I defining a wrong host?


Thanks,
