How long before next glibc release?  This problem could be painful for folks 
that are using gfortran for real world applications who are not aware.

Maybe we need to add an errata file to the tree and add a message at the end of 
configure to remind people to read the errata file. This would go for all of 
gcc, not just gfortran.
