Kurt,

  uh, my original suggestion to check the installed xmkmf was directed
to Frank who wasn't very lucky with his Fortran compiler.
Now for AIX, for which I'm actually compiling R at the moment.

I'd like to take you up on your offer, especially since I can't create
the configure file out of configure.in.  
Attached is (hopefully) a patchfile that updates configure fo AIX.  It
also patches the Makefile.in in src/library/modreg/src and it contains
ldAIX4 which is a script for the aux (in R-0.64.1) directory.
(I've put the patch at: www.ece.cmu.edu/~tov/public/R-on-aix42.patch)

Something like the following in a clean R-0.64.1 directory should
work:
$ cd R-0.64.1
$ patch -b -u -p0 < ../R-on-aix42.patch
$ chmod +x aux/ldAIX4
$ mkdir build && cd build
$ # force native compilers:
$ CC=cc ../configure --with-f77 --with-x --without-gnome
$ make

This still leaves the problem with R SHLIB.  AIX needs a file with
symbols that are exported from the main program (R.binary).  A "make
install" should store this file in RHOME/etc/main.exp or somwhere
close.  Lemme think about how to work with in installed R.

A final "make test" runs smoothly up to ../../tests/print-tests.R.
There are some diffs with the length of printed doubles, like,
< [4,] 1.7976931348623157e+308
---
> [4,] 1.797693134862315708145e+308
So the printed number in AIX is shorter?  Any comments?

Thanks,
  -tom
