Subject: R-alpha: Fortran (linpack and eispack are dead!)

I am currently in the process of removing all traces of fortran from
the R distribution.  This is mainly to help the porting effort to
Windows and the Macintosh.  To do this I have recoded the routines we
actually use from Linpack and Eispack in C (I think I can now
outperform commercial translation programs!).  The question remains of
whether and how to provide general functionality.  I see a number of
options.

1)  Provide a subset of LAPACK (which subset?).

2)  Provide all of LAPACK in a statically loaded form.

3)  Provide all of LAPACK as an add on in DLL form (this will not
    work on all platforms).

The range of platforms and need we are aiming at is quite large so it
may be impossible to satisfy all needs.  Anyone care to comment?
