[R] Cross build Makefile

[Iago Mosqueira]

Hello,

I am trying to use Yan and Rossini's Makefile for cross building Windows
versions of R packages in Linux with R 1.9.0. When compiling R with the
mingw tools I get an error about expm1 being undeclared when first found
at src/main/arithmetic.c:1019

If I fiddle a bit with it later on I also get errors about log1p bein
undeclared.

Any idea what should I look for?

I am using R 1.9.0 in Debian, with R-mathlib avaliable, and gcc 3.3.

Thanks,
