The search paths are different for the main compile and for packages.
The idea is that f2c.h is _not_ the correct one in general: it is an R
legacy. So the standard search is not finding f2c.h, and the solution
is to fix that.

I think problems with different f2c.h only arise on machines for which
long != int, but no guarantees.  The one in f2c.h will suffice for simple
uses.
