Hi Steve,

This patch allows comparison of numeric values with Holleriths. This

support does not have such an option.
IMHO.
Has the comparison of a numeric value and a hollerith
ever been allowed in a Fortran standard? If the answer
is 'No', then you should (1) put the comparison behind
an option, and (2) have gfortran issue an error without
the option. If this is a DEC extension, then put it
behind -fdec. If this misfeature is not a DEC extension
but allow some ancient piece of code to compile, then
put it behind -std=lagacy.
I concur.
Additionally, please put in a test case which confirms that
an error is indeed emitted without that particular option.

Thomas
