Accepts invalid?

Hi,

This example code defines a couple short strings and hands it to a
subroutine that takes longer strings. A certain other commercial
compiler Intel flagged it as an error. Gfortran did not flag a warning
or an error.

1.  Is this truly invalid code?

2.  Does/Is there a way to make - gfortran flag an error?
    When I checked on a gcc mainline build it went through without a
hitch.
    A certain other commercial compiler (Intel) flagged it as an error.

3.  Language related: Is there a better way to convert cases in Fortran
these days?

Thanks,
Ed Smith-Rowland
