alphaev67-dec-osf5.1 showed warnings like:

/home/jayk/src/gcc-4.5.1/libgfortran/io/write.c: In function 
'nml_write_obj':
/home/jayk/src/gcc-4.5.1/libgfortran/io/write.c:1504:8: warning: array 
subscript has type 'char'

Committed as obvious to the trunk (Rev. 163469).
I don't plan to fix it on the 4.5 branch - but feel free to backport it.
