Hi, Everything seems to be ok in this patch, except for minor typos in documentation: REAl -> REAL, alignement -> alignment.
It would also be nice to extend the type conversion facility to include -fdefault-real-16, -fdefault-double-16, -fdefault-real-10, -fdefault-double-10, and add conversions for logical types, to complete the conversion table. These are not very commonly used (except for -fdefault-real-16, -fdefault-double-16, which would correspond to -r16 and -autodouble flags in some compilers), so we should be fine at this time. Thanks to everyone for making this work!
