I have a niche reason to build a 32-bit version of R. I'm playing with F#
on Mono on Mac OSX, and specifically with Deedle, a data frame

higher-level way to provide a set of functionality, types, and data to F#.
RProvider links to the local R library similarly to rJava. Since Mono is
32-bit by default, and its IDE, Xamarin Studio, runs only in 32-bit mode,
it's thought to be much easier to recompile R for 32-bit mode than the
whole of Mono.
Looking at the sources, there's no obvious way to switch to 32-bit. The
gfortran.pkg (4.2.3) seems obsolete; I've configured the default setup
So? At least it includes a 32-bit compiler (by default if I understand
the version you are using).
successfully only after installing gfortran 4.8.2 via brew. But setting
CPPFLAGS="-arch x686" reports that Fortran mangling is messed up.
You need to specify a 32-bit compiler. AFAIK -arch is specific to Apple
front-ends, and the value is i386, not x686.
If you build multilib GCC from the sources, the flag needed is -m32.
This *is* all in the relevant manual.
So how do I build me a shared R library for 32-bit mode?
