[R] compiling R with gcc 3.2 on Solaris

[Paul Gilbert]

I am trying to compile R 1.6.1 with gcc 3.2 on Solaris (Sun OS 5.8) and
configure gives me:

checking whether g77 and gcc agree on int and double... configure: WARNING: g77
and gcc disagree on int and double
configure: error: Maybe change CFLAGS or FFLAGS?

Complete output from configure is below. I am not setting CFLAGS or FFLAGS, but
can someone suggest what I should set them to (or is this some other problem)?

Also, the reason I am trying gcc 3.2 is to use -m64. Do I need to specify this
explicitly or will configure choose that automatically?

Thanks,
Paul Gilbert
