[Bug fortran/26444] New: gfortran does not compile cp2k

[jv244 at cam dot ac dot uk]

gfortran currently yields ICEs trying to compile the cp2k code. To make it
easier to address these, I'll attach a 'preprocessed source'. 

cp2k.f90: In function ‘timeset_full’:
cp2k.f90:10751: internal compiler error: Segmentation fault

I've decided to make it the full program, so that it can be compiled into an
executable. As soon as gfortran does generate a correct executable, I'll setup
a nightly or weekly regression tester (frontend bugs / compile time /
performance).

The code is quite standard conforming and portable, but as is usual there are a
few exceptions (best documented by the NAG f95 command line options needed
-dusty -dcfuns -mismatch_all -kind=byte and that it is missing some extensions
such as iargc or etime) , these are very common and ifort,g95 just compile with
the defaults. On the other hand the thing as a whole seems quite challening,
two version of xlf90 run into an ICE, and pgf90 is generating .mod files for
about an hour now (g95 compiles in about 10min).
