[Rd] fortran data statement

For the record:

I had an inquiry about a problem with the function lm.fit.recursive in my quantreg package on a 64bit gentoo linux system. After some debugging the problem was traced to the fact that on this system g77 took the view that the statement:

        data one/1.0d0/

meant that the symbol one should take the value zero. Replacing such data
statements with their parameter statement equivalent, resolved the problem. This obnoxious behavior seems not to be news to the gcc folks,
see http://gcc.gnu.org/ml/gcc-bugs/2002-08/msg00195.html but they don't show any inclination to fix it either. I am in the process of updating my packages and thought that others might appreciate a warning -- or,more likely, enjoy the schadenfreude of enlightened
C-aphones.
