[Pw_forum] One minor bug, one not minor and two questions

[Laurence Marks]

Agreed. One could (maybe) write a macro for this but it would be way
too specialized. Just removing the over-ride should enable the user to
specify it; most cluster sysadmins should have this posted or one can
use the ifort linking guide.

N.B., I would test myself, but at least on the cluster where I have
PWSCF installed it complains that at configure.ac:30 the language is
set as C not Fortran. This might be a bug in the autoconf I have there
or real -- getting the language set right is a pain and I've had
problems with this in the past for other code.
