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