[Patch, Fortran] PR fortran/37199: Wrong code for function returning array

[Daniel Kraft]

Hi,

this is a proposed fix for PR 37199 where gfortran produced wrong code 
for a function returning an array.  For details on the problem, see my 
comments on the PR at http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37199.

This patch sets the array-spec on new_sym when doing interface-mapping 
and I had to include an additional condition for remapping ISYM_SIZE's. 
  I'm not sure if there are other places where such a new condition 
would technically be needed.

I'm not really an expert on the code touched, though the fix looks more 
or less good to me.  No regressions on GNU/Linux-x86-32, as well as 
passing the test from the PR of course.  And additionally, with this 
patch the HOPPET-package mentioned by the reporter now builds and runs 
the test-suite fine (which it didn't do with gfortran 4.3.1 for me).

What do you think about this fix, does it seem ok?  Or should I try to 
find some other patch?

Yours,
Daniel
