The CHANGES file in Windows?

rw1020
======

This version has been compiled against msvcrt.dll not crtdll.dll.
This gives small speed increases and generally more accurate results.
Packages compiled against crtdll.dll will still work (as far as we are
aware), but for best results should be re-compiled.  (A few packages
need to be re-compiled for 1.2.0 on all platforms, and any that used
malloc directly need to be recompiled on this one.)


Did you re-compile against msvcrt?  We have compiled up a lot of Frotran
code, both in R itself and in contributed packages, and seen only
small changes.  (Quite a few Fortran-based packages do use malloc directly
and so do need to be re-compiled, but they will not load otherwise.)

The recommended compilers have changed: see README.packages.  As far
as I know the old ones still work.

That's not going to tell you about changes, let alone platform-specific
ones.
