 redirection of stdin

Thank you for the suggestion, which had already been tried.  It does not 
always work as the static library is not compiled with -fPIC and so cannot 
be linked into DSOs to be dlopen-ed.  E.g. it fails on x86_64.

Being unable to correctly compile a GNU project (R is a GNU project) with 
silent errors seems to us to be a quite serious bug.  It make 
gcc4/gfortran unusable on a common platform (x86_64), and easy to break on 
many others. (R is an extensible system, and loading any extension 
compiled against a dyanmic libgfortran leads silently to incorrect 
results.)
