Thanks for the review.

Regarding the spacing issue: That seems to be a quoting bug in 
Thunderbird. The local version of patch and the original email seem to 
be OK: http://gcc.gnu.org/ml/fortran/2011-02/msg00059.html

Yes, the idea seems to be that a PURE function does not affect its 
arguments while such a requirement does not make sense for subroutines. 
Thus the standard has:

C1276 The specification-part of a pure function subprogram shall specify 
that all its nonpointer dummy data objects have the INTENT (IN) or the 
VALUE attribute.
C1277 The specification-part of a pure subroutine subprogram shall 
specify the intents of all its nonpointer dummy data objects that do not 
have the VALUE attribute.

Committed as Rev. 170060.
