I do know that Prof. Ripley, Peter Dalgaard and Martyn Plummer have spent a fair amount of time on this issue and there are notes in the R-admin manual regarding some of the gcc 4.x problems. There were also various discussions on r-devel and offlist over the past several months about these issues, later including Tom Callaway from Red Hat, who is the Fedora Extras package maintainer for the R offerings in those repos. These had to do with the various compiler, optimization flag and later BLAS/LAPACK issues. The current gcc version on a fully updated FC4 system is: $ gcc --version gcc (GCC) 4.0.2 20051125 (Red Hat 4.0.2-8) and I believe solves the prior issues related to 4.0.0. R compiles fine on my fully updated FC4 system and passes 'make check all' without error.
