[Bug fortran/45170] [F2003] allocatable character lengths


http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45170

Is there any chance that gfortran 4.7.0 will support allocatable character
lengths? Using fortran for text processing has been painful since time
immemorial and this little feature is a huge leap indeed.

Unlike iso_varying_string you can combine allocatable characters to all other
built-in features of fortran like print *,string. Additionally, as soon as it
is allocated, you can assign it to a non-allocatable dummy characters so no one
but the supplier has to care about whether it is dynamic or not. That's why it
is much more powerful than iso_varying_string.
