The thing is, it does work on some platforms -- I do test i686 RH8.0 (updated with gcc 3.4.1) from time to time and it looks like I tested 1.9.0 during beta test. So `make check' is the only reliable test. (I've just run the current R-devel to cross-check. It runs into the infinite-loop in LAPACK problem with gcc >= 3.4.0 though, with the same fix.)

I suspect f2c on a 64-bit platform is a bad idea as int != long. We could detect that.
